Somebody asked me to look at the de-activating problem of the extended view add on.
It runs now without deactivating itself.
I don't know exactly what the fix was. But this is what I did:
1 throw away the extended view plugin
2 download fresh via the add-ons menu item in the time.ly main plugin
3 install and activate
4 in the main plugin/settings go to the 'add-ons' tab and check the "show footer" box for extented view add on
I suspect it is step 4 that does the trick: in my logic the add on doesn't register... the checking of the box gives the main plugin a living connection to the add on
