What is [Matrix] Sticker Helper?

I created this app for the pursuit of an user-friendly way of managing sticker packs on Matrix, that could also work well for other people, after finding the maunium/stickerpicker import procedure uncomfortable.
Read more (and follow the development I guess?) at https://octospacc.altervista.org/tag/matrixstickerhelper/.

How can I add sticker packs to my collection?

To add new sticker packs to your collection, you can use the dedicated section to input an URL pointing to the JSON data file (in the format used by maunium/stickerpicker) of an already existing collection (index.json) or individual pack (created by other users, or from your backups).
The ability to create sticker packs by uploading files from your device's storage will soon be available, as well as from the messages sent by other Matrix users.
Importing stickers from LINE or Telegram is planned for the more distant future.

Stickerpicker information

This project is not a substitute of maunium/stickerpicker, and is not affiliated with it, but rather complements it. 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.
