Refactor savings screen
Things done in this MR:
- The
CliveCheckerboardTable
widget created earlier was used on the savings screen. - Change css classes and id`s to be clearer.
- Follow the convention that we use only protected attributes - not private ones.
Partly satisfies: #170 (closed), #163 (closed)
Requires: !314 (merged) (to check if scrolling is displayed correctly)
