Thank you, and sorry for soooo late for replying.
Time counter could be implemented in the future.
Add-on versions are also possible, I know it's a more accessible way... but even making a single icon bothers me 😅
Cool!!! Is there any way to also make time counter shown?
I'd also love to see this as Chrome/Firefox add-on but it's not necessary
