Issue Description

The tap that opens when clicking the "Manage Columns" menu has a fixed size and therefore cuts off long column names.

Steps to reproduce

1. Create a column in a class that is longer than the width of the "Manage Columns" tab
2. Open the "Manage Columns" tab

Actual Outcome

Column name is cut off

Expected Outcome

Tab should adapt its width to fit the longest column name, maybe up to a max width, and only then truncate the name.
