TODO:
* more error handling and debug logging
** manage consistency between modal errors and messages in debug log (probably will need a SpaccDotWeb function for that)
* immediately show an image after uploading in the grid
* allow reordering, renaming, deleting stickers and packs
** maybe by default show the sticker packs in the same order in the list as the picker does, or at the very least commit them with recent stickers being at the beginning of the list
* import from line, import video telegram stickers, import video files, import files from URL
* save a linkback to a sticker pack in every single sticker optionally, allowing stickers to be copied, possibly from matrix.to URL
** set this and other options as persisting in the user account data
* fix sticker reimport protection not working?
* in a lot of places that only do HTTP(s), handle also mxc:// URLs
* open graph, PWA things (webmanifest, worker for offline support)
* fix stickers from file/Telegram in demo mode (we must store the data uri img srcs in RAM for viewing)
* UI improvements like blocking buttons in inconsistent states, adding more feedbacks for long operations
** more loading messages and overlays
** fix race conditions between actions like user going back while app is committing or loading packs (including commit button)
* compatibility build / add polyfills
* multilanguage?
* gif encoding without webserver (without ES import)
* APNG encoding, if it works
* allow copying the JSON (and optionally reuploading images? probably not needed tho) when importing existing Maunium packs

🃏️ [Matrix] Sticker Helper <a name="version" title="Click to show changelog" href="javascript:;">WIP Version</a>,
created with 💕️ and ☕️ by <a href="https://hub.octt.eu.org">OctoSpacc</a>.
<br/>
Made possible by <a href="https://github.com/maunium/stickerpicker" target="_blank">Maunium sticker picker</a>,
brought to paper thanks to <a href="https://www.getpapercss.com" target="_blank">PaperCSS</a>.
</p>
<p>
<b>Note</b>: importing stickers from files/Telegram is currently experimental, and error handling isn't the best.
Make sure that your Internet connection is stable when uploading/importing stickers, and be patient if it seems like the app does nothing for some time. Don't navigate around the app when stickers are loading or importing.

<p>Help and Information</p>
</summary>
<h3>What is [Matrix] Sticker Helper?</h3>
<p>
I created this app for the pursuit of an user-friendly way
of managing sticker packs on <a href="https://matrix.org" target="_blank">Matrix</a>,
that could also work well for other people,
after finding the <code>maunium/stickerpicker</code> import procedure uncomfortable.
<br/>
Read more (and follow the development I guess?) at
<a href="https://octospacc.altervista.org/?s=%22%23MatrixStickerHelper%22">octospacc.altervista.org/#MatrixStickerHelper</a>.
</p>
<h3>How can I add sticker packs to my collection?</h3>
<p>
To add new sticker packs to your collection, you can use the dedicated section, which offers 2 options. You can:
</p>
<ul>
<li>
Either leave the optional text field blank to create a brand-new pack, to be filled with stickers by importing media files;
</li>
<li>
Or, to import packs from one of a few different supported sources, input an URL. Supported URLs are:
<ul>
<li>
Those pointing to the JSON data file (in the format used by <code>maunium/stickerpicker</code>)
of an already existing collection (<code>index.json</code>) or individual pack (shared by other users, or backed-up by you),
assuming the file is fetchable with CORS restrictions.
<br/>
The URL must begin with <code>http://</code> or <code>https://</code>.
For example, <code>https://maunium.net/stickers-demo/packs/pusheen02.json</code>.
</li>
<li>
URLs of Telegram sticker packs, either Static (PNG/WebP) or Animated (TGS). Video stickers (WebM) will be supported in the future.
(For the technical details, see <a href="https://core.telegram.org/stickers" target="_blank">https://core.telegram.org/stickers</a>.)
<br/>
The URL must be in the format "{optionally, <code>http://</code> or <code>https://</code>}<!--
-->{<code>t.me</code> or <code>telegram.me</code>}<code>/addstickers/</code>{name of the pack}".
For example, <code>t.me/addstickers/FishPuffer</code>.
</li>
</ul>
</li>
</ul>
<p>
Currently, you can import common picture files (JPEG, WebP, PNG, GIF) from your device's storage as stickers.
Sooner, you will be able to also import media files from URL, as well as importing video files (like MP4) for automatic conversion into GIF.
<br/>
Importing stickers and packs from Matrix messages, or the LINE store, is planned for the more distant future.
</p>
<h3>Stickerpicker information</h3>
<p>
This project is not a substitute of <code>maunium/stickerpicker</code>,
is not affiliated with it, and doesn't use any part of its code, but rather complements it.
<br/>
It sets that up as the sticker picker integration for your Matrix account if you don't have it already,
and allows you to manage your sticker collection in a way that is fully compatible with it, but without the manual setup.
</p>
<h3>Open-source, licensing, security, collaboration</h3>
<p>
This app is open-source, and licensed under the
<a href="https://www.gnu.org/licenses/agpl-3.0.html" target="_blank">GNU Affero General Public License Version 3</a>.
To modify the app, or to check its code for security reasons, you can simply "View Page Source" in your browser.
<br/>
This project additionally relies on the following third-party libraries:
</p>
<ul>
<li><a target="_blank" href="https://gitlab.com/SpaccInc/SpaccDotWeb">SpaccDotWeb</a></li>
<li><a target="_blank" href="https://github.com/gram-js/gramjs">GramJS</a></li>

</ul>
