Adding extension API for general file editing

[hajdam]

Hi,
in my spare time I'm working on some simple hex editor, hopefully I'll get to adding some content analysis and dissasembler this year.
I tried to create extension for Ghidra, but I didn't find usable way to make pure hex editor behave as a separate tool in Tool Chest being able to edit general files.

I understand it's maybe out of scope for application's intended functionality, but would it be possible to add or modify extension API to provide such capability or would it be acceptable for me to create merge request with such changes?
It's also possible I was just unable to identify proper method to do so.

Best regards,
