Thus far to my knowledge other commands work. The only other commands I know of, however, are manually set quick texts which work fine I think. I do not use them so I'm not sure.
I also have no idea what kind of list you mean. It's never shown a list for me when I type the /, not when I first downloaded it years ago, and not right now...I didn't even know that was an option, or where to find that option under settings.
And yeah, my friend can send /me commands perfectly fine, and we're using the same versions of everything.
I primarily use Plus for tabbed chats, encrypted message logging, locking, and /me capabilities. Most other features I don't bother with
I'll poke around in the settings and see if I can find that list thing you mentioned...maybe if I can find it that will make it work?
Edit: The new version seriously changed the preferences menus, so I had an odd time navigating it when I reinstalled it last night. But I did manage to find that box and checked it. So far it seems to work! Thanks for your help
