Thanks for the feedback. This was really more of a first attempt. (The mono-spacing was to better align the information into columns and support -> Title: xxxx / yyyy tabs ... and would look good up to 9999 tabs)

I have released v0.9.9 to add a compact view option that you can access by clicking on the addon button.

As for the Window numbering, I am just asking the API for a list of windows and I traverse them one by one assigning them 1 thru n. From an API perspective, each window just has an ID assigned to it but those numbers mean even less to the user. I could sort the windows by the number of tabs in each THEN assign them 1 thru n, but not sure how useful that is.

As for the "New Tab" description, please see: https://github.com/irvinm/TST-Active-and-Total-Tabs-Counter/issues/3. I could use more info please.
