Hi, I'm glad that you're enjoying the game so far :)
1. I can try that adjustment. It should be pretty easy to add commas to all the currency numbers in the game actually because of the way I designed the currency display.
2. A mouse-over popup for the info bars, I'm not sure if I have the functionality for that but I will investigate. Maybe there is another way to display the information you want as well. I will think about this more.
3. You can see the type of work experience by clicking the "Character" button on your profile panel. It should be under the Experience heading.
Thanks very much for your suggestions, they really help me see the game from the player's perspective.
