When you go to the channel settings window by clicking on the button to the left of the channel topic, there's a tab named "Ban list" which lists the channel bans, and has two buttons at the end: "Remove ban" and "Add ban". The "Remove ban" button removes the currently selected ban. However, I didn't find a way to select and remove multiple bans in one operation.

I was expecting to be able to select a range of bans or multiple bans by holding the Shift or Control keys, respectively, and then be able to remove all of them by pressing "Remove ban". Being able to remove multiple bans this way can be faster and may not flood the channel if Konversation was able to unban multiple masks in one single operation, like when you type something along the lines of:

/mode <channel> -bbbb <mask1> <mask2> <mask3> <mask4>

Greetings and keep up the good work. Konversation is really cool!
