    1. UI change requestOpen

      On the left, is the "Open" screen for Cosmic Text editor as it currently is. It feels a bit like a wall of text, and the prominent separators contribute to this effect as well. Because there's so much going on, it's a bit hard to pick out the important bits of information. So in…

      I have 3 screens and the icons that were there before the upgrade were still there, but I have the following issues: 1. The icons appear on all three screens (so I have three of each one now) 2. I’m not able to reposition the icons other than sorting them I would very much like…

    4. [Bug] Ctrl+V pastes previously copied text instead of latest copied fileClosed

      If some text is copied first, and then a file is copied or cut, attempting to paste using Ctrl+V sometimes pastes the previously copied text as Pasted Text instead of pasting the file. When the most recent clipboard operation is a file copy/cut, Ctrl+V should paste the file, but…

    7. File transfer ETA & data speedOpen

      Right now, file transfers only show percent completed. It would be nice if the progress also showed in ETA to completion (hours & minutes) as well as speed (MB/s, etc).

    8. [feature-request] please add navigation with page-down page-upClosed

      please add navigation with page-down page-up when in a folder with a lot of files or folders navigate by mouse or slidebar or scroll down is inefficient, page-up and page-down keys are natural to use in that case.

    9. [Feature Request] Add an "Open File As Root" option in right-click menuOpen

      I would like to see an option in the right-click menu in COSMIC that enables you to open a folder with full root privileges, so that you can modify the files that are contained inside. This is something that exists in Cinnamon, and I've got some screenshots of this being used. I…

    12. Progress window for file operations disappearOpen

      The progress window for file operations disappears if the cosmic-files window is closed, but the operation continues. The problem is that it's not possible to return to the progress window to monitor it.
