Thanks for the feedback.
In the last update I've added an option to change the font size of annotations, it should help a little. In theory I could implement a smarter algorithm to place them, but to be honest I always considered labels to be a feature of little importance. As far as I can judge people don't use them much. When there will be more interesting generated neighborhood names I'll try to do something to fix the situation, maybe I'll add map legend as an option.
