The problem is fixed (I forgot to change the bug status). The icon is small because Thunderbird doesn't ship an icon that fits on launcher (I think the larger icon available is already being used).
The problem with highlight on wrong place is reported on bug #761465. ** Changed in: unity Status: In Progress => Fix Released ** Changed in: unity (Ubuntu) Status: In Progress => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/754095 Title: Check Email dash icon doesn't open default email client -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
