Previously when a tab was detached the numbers stayed the same. I tried various methods to get the numbers to update, with no solution. This patch fixes a variety of tab behaviors when moving, detaching, attaching etc. There is a small delay between the numbers updating. About 300ms — Once I confirm for certain this delay isn't needed and all the issues have been resolved, I'll remove the delay in the next version. Everything seems to be working properly in this version. There are no issues with multiple windows, tabs can be detached, reattached, closed, reopened and the numbers correspond correctly.
