Like it is already done for files. For media players it would be great to have the possibility to open a folder with a player. (Add to playlist) E.g. nautilus already has such a feature ( possibly could be used as implementation reference )
Created attachment 7698 possible fix Attached a patch, fixing the issue. - "open with" will be shown on folders (one or many folders/files selected) - list of applications which can open folders will be shown in submenu - despite for other file types, always "open" will be shown as first item ( like before ) - despite for other file types, it will not be possible to change the default application type which opens the mime-type "folder" I would be happy for testers ! Since currently there is a feature-freeze on the master branch, applying this patch will be delayed until thunar 1.8.0 got released.
Patch is incomplete: - "open with" missing for right-click on shortcut/tree-view - "open with" missing for pathbar (as well UCA's missing .. there is already an issue for that )
Related, useful for testing: Here way to wipe the preselection(mv, since possibly it wipes more): mv .local/share/applications/ .local/share/applications.backup
