In my opinion the timer should show both minutes and seconds because ATM it's just too inaccurate. For example, when you have 2 minutes and 30 seconds left, the timer should be 2:30, not 2m. Otherwise a great mod.

I'll take that under consideration.

The problem is that if the text gets too wide, it does not neatly fit in the icon. So a time like 11:30 would be 5 characters long, and that would be a problem. Right now the maximum length is 3 (like in 11m); but possible I can get 4 characters to work (so having like 9:30 would be ok, but for 10 minutes or above, keep the 10m as of now).

Another aspect is that having the seconds count down feels a bit stressful. It makes sense when there is just a short amount of time left, but having like Hero of the Village for 20 minutes and having every second count down would not make a good UI, I think. So maybe seconds should start showing when it's like 3 minutes left, or so.

This might be the tipping point for where I have to add a configuration screen to the mod. :-)

I will not implement this. Trying to squeeze in 4 or more characters will not look good.
