Also spelling mistake in the poll (scrilling ).

OmnomIRC used to support mousewheel, but Netham45 had to remove it in extremis because it annoyed the shit out of most members when they tried to scroll down through the page. OmnomIRC scrolling would override page scrolling so people were unable to scroll up or down unless they hovered elsewhere. Of course, back then it was worse because when Omnom loaded, it was at the top of the chat rather than the bottom but even if it starts at the bottom it would still be annoying when scrolling back up.

While this is true, a few people were annoyed by it, I would say the majority of people were more annoyed that they couldn't scroll with the mousewheel. I still think this needs to be an option.

Perhaps the first  time / few times / until "do not show again"  omnomirc loads for a person it can bring up a notification (similar to what happens when enabling extra channels), emphasizing the options somehow?

Relating to the scrolling, maybe it can only happen if the mouse has been over the chat for x seconds, otherwise it scrolls the page.
Idk how doable that is doable tho.
Or maybe the user would have to click the chat window first.

For the scrollbar in its current state, can the track be changed to the border color (matching the theme ofc)? Other than the text it's the only black thing, so it draws focus and looks kind of weird

I mean the first time a person uses omnom, it says something along the lines of "look there's an options menu."

I actually like the notification pop up like on other sites, just as long as it only appears over OmnomIRC and actually disappears for good until you deleted your browser cookies, and that in every browser. I hate how on Reverbnation those notifications continue appearing even after clicking "Do not show this again"

um, i don't get it

Oh, i was confused because of the irc client open
So yeah, nice!
