#8 Show activity of a hidden client on the tab

[Alexander Kremer]

Assume we have a group with 3 terminals and thus we have 3 tabs and only one client is selected at a time. Basically this means that any activity on the other two clients is obscure.
We could add a possibility to tune the monitoring of the activity.. the simplest case is adding [*] to the title of the tab for the corresponding client if it had activity while hidden from user's eyes.

Note: Similar functionality is implemented in GNU Screen, the well known window manager for the console. I would find it very useful.
