The search function in AdiIRC is powerful. But I think it can surpass mIRC's own search function. (For the record, I'm referring to the CTRL+F search function that allows you to search the current buffers for a string of text, using regex or exact matches if needed.)
Now, I'm not a developer, and I certainly don't know how hard this is to implement, though I find it would be very useful, and maybe you might too. Adding three checkbox options to make the search function better.
Channels: This checkbox will cause AdiIRC's search to search all open channel windows within a single server for the given string of text.
Privmsg: This checkbox will cause AdiIRC's search to search all open privmsg windows within a single server for the given string of text. Can be used in conjunction with the Channels option.
Global: This checkbox will allow AdiIRC's search function to search for a string of text in all windows across all servers. By virtue, this automatically invokes the aforementioned Channels and Privmsg search options.
