This PR breaks the widget. Just open it, enable optimization, and decrease To. The number of rows in the table doesn't change.
The problem is that return in line 217 should also be changed to return True.
As a punishment :), add a test that check this (e.g. a tests that currently fails if the user does what I described above) before fixing this problem. :)

Say that mainArea is hidden. If optimization fails, main area won't be shown and updated. This is OK.
What if mainArea is currently shown and contains some data? If optimization fails, it won't be hidden, but it won't update either...
Issue
When there is less rows in a data than selected (from - to, second option) the widget crashes.
