I think I will try Gomuks, since I now also tried Fluffychat, but scrolling felt weird and on a touchpad had the tendency to swipe left on messages to reply instead of scrolling down and I was unable to resize or close the channel info and channel list, or change its font size (there also appears to be no settings button). Maybe the CLI based clients will be more suited for me, since I also don’t mind using irssi for IRC (but it should be noted I also have no problems with graphical IRC clients like hexchat or others, which work perfectly fine on my machine).
