Annoying system tray icon
Now Opera has a system tray icon. Nice. It also does have a little mail icon on top of Opera's icon, probably indicating new messages (like that little exclamation point at mail panel icon). For our deception, it does not (inconsistent interface!). It appears to display the existence of unread message. Hey, I have tons of unread messages I won't read, so then I can't get rid of that mail notification at my system tray!
Since I can't get rid of mail icon, I want to get rid of the entire opera icon at system tray. Let's try it! Let's look for an option to disableit at preferences dialog. Found it? No. Let's try to find an option at some menu. Found it? No. Let's try again, looking more carefully. Found it? No. Finally, let's try opera:config. It must have an option to disable it. Found it? NO!!!
People at #Opera told me to use -notrayicon parameter when launching Opera. Though this works, this is not a good solution, because this means I need to change all my Opera shortcuts, which includes one at wmappl, plus two at fluxbox menu, plus all other shortcuts at other window managers. But what happens when Opera is launched by another application? Of course, it will not have that parameter, and it will display the f... the fine icon.
I've submitted this issue as bug-220000: There is no option to disable system tray icon.
