Glad you're enjoying the game! There is a UI Scale slider in the options which will make everything (including the text) larger/smaller, which may do what you need. I'll keep the rest in mind for the next update though, as it's planned to be focused on UI/UX.
The map is definitely going to get some upgrades sooner or later. What's in game right now is the minimum, super basic map just to get something to help players out. Hopefully I'll have time to put some work into it with the next update, but I wouldn't be surprised if the map continues evolving over several updates.
