This is mainly cosmetic but also has some usability (ergonomie) improvements: the various report dialogs (Statistics, Trends, Balance, Budget) would benefit from the use of linked button styles, hiding/showing buttons based on the context, and optionally some client-side decorations (headerbars).
For example, let's take the "Statistics" report (and the other reports will have the same issues). What could be done to make it visually clearer:
- The "List", "Column" and "Donut" (and Stacked bar charts etc. for other reports) buttons should be linked buttons, just like the "Category" vs "Subcategory" linked buttons in the main window's "Where your money goes" section.
- The "[Toggle] Detail", "Toggle legend" and "Toggle rate" buttons should not be set (in)sensitive, but rather set (in)visible depending on the context/mode. It doesn't make much sense to have them shown at all time. Hiding/showing them depending on the mode will make their relationship with the mode clearer. Slight caveat/gotcha: for the "Details" button, if no row is selected while in "List" mode, it should be shown but still insensitive.
- Bonus points: maybe you could use client-side decorations (GTK3's headerbar feature) to put the main mode toggle buttons in the titlebar?
I switched the list|bar|list and other to radio (what they should have been)
any other non relevant widget is now invisible instead of disabled according to context
no headerbar (I don't like this)
a future ui/ux layout will come later on
