Many of us are long-time mIRC users, and occasionally we have to re-install mIRC on a fresh system. For me, it's always like this:
All goes well until mIRC pops up the Favorites, and of course, I'll type my channel there (to the "join" prompt), only to realize I want to remember this channel name. Well, it's not remembered automatically, and even pressing add instead of join doesn't complete the channel name and network to the query what comes from add. This is a some kind of frustration for people who have their favourite channel named longer than "ass", as they have to re-type channel name and even choose the network again.
This sure is a minor thing, but it's also very easy thing to fix and it eases the life of people who uses mIRC again and who installs the client on their new systems, or systems they are using in work or at friend's place.
I'm suggesting two features:
1st, any joined channel should be always included to favorites, also remembering the network used for the particular channel.
2nd, the "add" button should include data typed already to the "join" line, as this most likely is what user already wants to add after realizing his mistake with the UI.
