Be permanently idle to your friends on Gtalk / Google Talk with the help of gAlwaysIdle. gAlwaysIdle is not available from their home page as it seems to be temporarily down. You can alternatively download it from ESnips.
Note: I’m not sure who’s uploaded gAlwaysIdle at esnips, so download at your own risk.
Extract the zip file and you’ll find an .exe executable file. Double click on it and gAlwaysIdle will be installed.
Right click on you gTalk icon in the system tray and you’ll find options like this :
Selecting Always idle will keep your profile always idle and selecting Never idle will show your previously used status (other than idle).
A few things you to know before gAlwaysIdle works correctly :
1> If you are logged in to gTalk and GMail chat simultaneously, then you will be be able to set ‘idle’ state in GTalk.
2> If you are on audio or video conference with someone, then too you won’t be able to set ‘idle’ status with gAlwaysIdle.
