Column widths persistence and auto-scaling

[redcatbear]

Situations

Users select column widths in the two tables according to window size and personal preferences. Since they make the effort of changing the width, that should also be persisted.

Additionally we don't want to waste valuable scree real estate, so even if the users change column widths, this should work together well with auto-scaling.

Additionally WR should remember:

1. Window size
2. Scroll bar positions

Acceptance Criteria

1. Date, time and type columns are fixed-width, wide enough to display all entries without truncating them
2. The comment columns in both tables automatically use the remaining space up to the right border of a table
3. User settings on the variable width columns are persisted
