UI:
    * rename Save to Create Comparison? (or similar)
    * create a tabbed lower interface, to give more room to graphs
    * add a graph of no comparison and a potential 3rd with comparion (if chosen on first tab of data/numbers)

    * have a comparison management capability - somehow, at least be able to delete csets (can I put an x inside the menu? OR, have a manage button and pop-up?)

    * maybe a help/note/set of links somehow, to common things: e.g. macquarie int rate page, inflation source, etc.
        - also then could effectively take those "notes" out of db.py and incorporate, so that when I update stuff it gets done right
        - in fact, I *COULD* have a basic date check/workflow, e.g. its been more than X days since Y was updated, click here ... and it walks me through the manual update steps
            and when I finish, its datestamped until next time

For bills:
    * might need to be able to mark a specific bill as an outlier:
        - so we ignore the data somehow (think Gas is messing with my bills)
        - and even electricity, water, etc. for when we were away in Europe but mostly gas/elec
