As a vim user, it would be helpful for me if the editor provides vim keybinding. But I understand that it would involve a huge amount of work. So there may be a workaround:

Currently, if TikzEdt detects an outside modification, it prompts the user "Do you want to reload the file from disk". If there is an option of "always reload from disk upon outside modification", then I can just edit the file using vim, and preview the Tikz picture in TikzEdt.

I see no commits in this repo for years so maybe the authors aren't developing this project anymore. But do is there any guidelines on compiling this project? If so I can help writing the feature and PR. Thanks!
