Would the focus jump to the searched player in Available players for the purpose of right-clicking for info about him/her?
Or would the focus jump to the game he/she is in for the purpose of joining the same game?

Yes.

In fact, you could select a nickname in the "Available Players list" and if you don't move the cursor for a few seconds, a (yellow) tooltip would appear and display these infos :

HornyPeter57 is currently playing on "Nicolas' game"
Current rank: 26th
Best rank: 4th
Games played: "837"
Best hand: "Full house"
PokerTH version: 0.8

But if you would right-click on that nickname, this time, a context menu would appear and you would see something like this:

Join the game Robert is in or Join Robert's game

This right-click menu would only be displayed if there are empty "seats" in the game.

Just another idea : add a "reset" button on the "Internet Game" settings category screen.

Because, some players like to change their servers, if they want to reuse the default one, they have to manually enter settings.

A reset button could make this step easy.

But playing on the internet is usually self-explanatory, or you can look up what you need in the manual. If you need some advice on how to play poker, there is a lot of stuff about it on the internet too.

Another (unrealistic ?) idea

An option (button) to translate chat lines of the lobby-chat in other languages.

There could be a small button that would start the auto-translation of what people type (not all the past chat lines but just the current screen).

Pokerth could know what language is used, getting the value from the country flag of each player.

Of course there's a risk that a player doesn't speak in his native language, but that's quite rare.

I just wanted to share it with you, just for fun, cause i doubt it's possible.

EDIT : from our chat we had on IRC :
This would require a LOT of data exchange between the "google translator tool" and pokerth. They may not like all that data share.

Another option could let the user choose if he wants to quit a game (when it is already over) or stay in the Connected players list.
