waiting for gmail

I am trying to cleanup an number of my gmail filters and labels this morning. (Let me know if I should dive into the details of my system in the comments, I’ll skip them for now.) And, I am spending way too much time waiting for the ‘loading’ notification to go away.

gmail loading...

still working

I don’t understand why I should be waiting for gmail to finish processing the changes to labels on the front-end. Why can’t they do that in the background on the server side?
