+### Direct support for archive files
 
 No need to unpack your archive. Just drag'n'drop your file in the MARL window, and MARL will unpack it for you. This takes place in your browser's memory: no files are written on your disks. It's also strictly read-only: your archive file is not altered in any way.

+### Strictly in-browser only
 
 Everything takes place in the browser, with no communication with any server (once the page has been loaded). Your archive data is _not_ sent to any server. No analytics are included either.

+MARL should be fully accessible to keyboard users. It also has been optimized for Forced Colors (aka "High Contrast" or "Contrast Theme") mode. Last but not least, it should be accessible to screen readers.  
 Accessibility is a vast and complex topic, and there's probably room for improvement. Feel free to let me know if you have feedback or suggestion!

 MARL should work on pretty much any screen size, as low as 300 pixels wide (and possibly less).
