Converting @everyone and @role mentions.
If a mention applies to you, it should be converted to your nick (though still displaying the original intent).
For example. @everyone -> your_nick (@everyone): ...
Of course, most likely the clients people use do allow adding additional highlights per-server or even per-channel, so adding them from the client wouldn't be a big hassle (actually done that already myself). But I decided to bring up this and a few other minor improvements that came to mind.
Actually, @role mentions seem to be kind of hard to even figure out who they were meant for from irc side, since role highlights are displayed like <@&280335162884227073>
Converting these highlights would also allow to check if the user actually has the right to ping you this way.
The whole role part of api is not implemented currently. Bitlbee-discord is completely oblivious of roles atm because there was no good reason apart from not joining the channels you are not supposed to. This is another reason, but I suspect that I'll implement @everyone way before the @role pings.
I feel like at this point this would be a really nice improvement.
I like how slack irc gateway adds (cc: your_nick ) if the message should highlight you.
