I mean Edit - F4 - Open with associated editor. Users could choose default or custom editor there.
Add "Edit" options there, same as 'Open in ... program', to current option 'Browser > Open action'.
And add also 'Custom files' there, same as in 'Items displayed'.
Code: Select all
Open action     |Open in   |Edit in (with)
---------------------------------------------------
Images          |xnview    |custom - [C:\Program Files...\PhotoFiltre.exe]
Audio files     |xnview    |default editor
Video files     |xnview    |custom - [C:\Program Files...\VirtualDub.exe]
...
Custom files (*)|no action |default editor

Custom files (*) e.g. EXE BAT COM
[                    ]E.g:
