The channel central's topic form is quite small, I doubt I'm not the only one with that opinion.
How about making it a multiline instead of a singleline? It bugs me to scroll to both the sides, before getting where I want to be - Call me lazy.
Further more, on Quakenet they have some new channel modes available - and has been there for quite some time. Figured you guys updated with a checkbox or something, so the new channel modes appears in the channel central.
The new channel modes can be found at
