Hiya,
Would it be possible to add the ability to right click a file in a file explorer (i.e. finder etc), say "file.txt" and when you click "Open with Left" left opens the file directly? Right now all that happens on macOS is Left opens to the last file you had open (and then you have to open the file you want directly through the software).
I know this is Open Sourced, so if I get some time I might give this a go myself later; if so, I'll make a PR, but thought it would be a decent idea to ask here first :)
