The thing I noticed today was that, when you want to create a popup or a user-command for example...
There's a limit of 256 characters to it.
I have lots and lots of poups that I want to import to Xchat from mIRC (mIRC doesn't have a limit...I think...) and Xchat doesn't take input after 256 characters.
I don't know if it's a bug in Xchat or it's a gtk thing...but I'd really like that limit to be raised a bit...to...infinite? lol, that would work for me and many others too
You can check for yourself, create a new user-command or user-popup and c/p something more than 256 chars long...and see for yourself
I took a look at Xchat's code (for the first time
) to fix it and I had no idea what was going on (lack of comments?...I don't blame the developers, it's a boring thing to add comments anyways, but it's useful for new developers too 
)
So, I thought I'd post it the the feature requests section, someone please look into it
