I just looked into Keyboard shortcut reference https://shotcut.org/howtos/keyboard-shortcuts/ and discovered that Ctrl+Y should be shortcut for Redo, but it adds video track instead (Im running Win 10 Pro). Ctrl+Shift+Z works. Its a trifle but its a bit confusing for windows users.
Another thing is the shortcut to Append item to playlist (shift + c). Am I right that it for example should append trimmed clip to the end of playlist (this feature is appreciated for me)? It doesnt work for me this way. It just reset the trim markers to the start and the end of the clip respectively.
Thank you shotcut team !
