See time signature of selection.
I think it would be helpful/efficient if there was an addition to the little bar in the bottom left that told you what time signature your selection is in, This would just be a very small but still an update to the quality of life aspect of composing with Musescore. Instead of having to scroll all over your sheet to find the last time the time signature changed, you could just see it at the bottom, along with all the other values that are already there.

Switch to the horizontal continuous view. There you can see the current time signature on the left edge. Maybe that's enough for you.
Of course you can suggest a new feature ...
