### Adding an icon to the font file (e.g. for the floating menu)
1. Go to https://icomoon.io/app/
2. Go to "Manage Projects" from the menu on the top left.
3. Use "Import project" and select <code>fonts/selection.json</code> from Jitsi Meet.
4. Import icons (e.g. svg files) using the "import items" button.
5. Go to "generate font" and make sure the identifiers for the new icons are correct.
6. Download the result in a zip file using the "download" button.
7. Copy <code>selection.json</code> and <code>fonts/jitsi.*</code> from the zip file to <code>fonts/</code> in Jitsi Meet
8. Copy the class for the new icon from <code>style.css</code> in the zip file to <code>css/font.css</code> in Jitsi Meet (do *not* copy the whole file)
