Using Cosmic after using Gnome. It take getting use to it.

When comparing File Manager Gnome is definitely better. Once when I used Cosmic Files to move a file to trash it went into an infinite loop moving the file to the trash location the fans started roaring. Now, the server isn't moving any files to the trash for some reason.

Another issue is copy stuff to the clipboard seems to be hit and miss.
Some apps work just fine other apps don't work at all.

Have yet to open any issues against it because being new to it I'm not sure if it's me or the software.
