Show 'Open with' programs in Custom Filter > Open with

[Neuro-NX]

Currently, you are only able to choose the options to open file in either, XnView or Associated program. But I want to have all videos open in VLC, but from my custom script in the Tools > Open with list (see last paragraph).

Also, some users may not want or cannot change their default programs/file associations. so utilizing the Open With feature is an option.

It would be useful to simply click on a file to execute the 'Open With' program or in my case script (that launches the binary), rather than using ALT+1 or a button.

Using a script is more powerful, than merely launching the program itself, as it allows control over how and what gets executed; For instance, I created a script that not only plays a video in VLC, but if the file is .xnf can get the frameindex and start at that timecode. Will share the code in the General board.
