+### Drag and drop doesn't work in the Flatpak
+
+This is due to sandboxing limitations of Flatpak. The main Discord Flatpak has
+the same problem. If you still want to use drag and drop, you can disable most
+of Flatpak's sandboxing by installing
+[Flatseal](https://flathub.org/apps/details/com.github.tchx84.Flatseal) and
+allowing access to "All system files" under the "Filesystem" section.
+
+### Is there any way to add custom CSS / a theme?
+
+Yes, you can add all your styles into
+`~/.config/discord-screenaudio/userstyles.css` (or
+`~/.var/app/de.shorsh.discord-screenaudio/config/discord-screenaudio/userstyles.css`
+if you are using the Flatpak). But please note that due to QtWebEngine
+limitations concerning content security policies, you can't use any external
+files (like `@import` or `url()`).
