Bug 430242

SUMMARY
To see where my money's at, I view Operations and Group by > Category, then expand the categories I'm investigating. This works fine, but if I change the filter criteria, a different set of categories opens.

STEPS TO REPRODUCE
1. Open Accounts, double-click on an account to open its Operations in a tab.
2. Click the settings icon to the right and choose Group by > Category
3. Click some of the bold category lines to expand to show operations in that category.
4. Now click the "Show: ..." text and change the filtering, e.g. click All (accounts)

OBSERVED RESULT
When you change the filtering, a different set of categories is expanded. Perhaps it's count-based, so the 2nd category in the view is expanded even if the 2nd category shown is now a different one.

EXPECTED RESULT
Skrooge should remember which categories were expanded and expand the same ones after changing the filtering.
If that's too hard, then maybe it should close (un-expand) all categories.

ADDITIONAL INFORMATION

in the console whence I started it.
