I have recently been trying out Vim, and although I'm still a novice and the command mode can initially be a bit confusing/awkward, I'm learning to appreciate its power.

Can you add a Vi/Vim command mode to EmEditor, as the combination of EE with Vim support would make the ultimate editor.

There is a 3rd part plugin make this possible, but I don't remember the name of that plugin.

So, what's the name of the plug-in? can anybody help?

Just browse the Library here on the right side...

cannot find. Can you? I need a 64-bits one

Stefan is right, I found it, EmVi, in the online library of EmEditor plugins, and from there, I found the author's official page.

But I don't thinks there is a 64bit version available.

ToadLoadin,
Have you tried to communicate with the plug-in author?
I've tried via the plugin's home page (a 'write' button on the left sidebar), but it requires login in Korean, but I cannot familiar with...
Will the plugin support all the VIM natural plug-ins or just its native commands?

Sorry, I'm not familiar with Vi or gVim, so I never tried to contact the author of EmVi.

Perhaps you can post a feature request comment on the release post of the lastest version:

Hmm...
I cannot find a way to post/send comments neither on the author site nor on the plugin page in the EmEditor library.
Do you find a way to send comments there?
Thank you!
