I'm working on an Expense Tracking App and I need your feedback

Hey guys! Currently I'm work on a project that's going to help me track all of my expenses. I'm going to keep it as much as simple, but I'd love to hear from you any ideas, that can be implemented and be useful.

My plan is to build app with:

1. Clean and easy to use interface
2. An ability to add, remove, and navigate between records without using a mouse
3. Analytics by each month started from Salary day

If you wonder how it looks like right now then here it is. This is just a Home Page
