If you choose a Table Window for a given table to see the comments on columns, you might face the problem, that a long comment is not fully displayed and can't be accessed as a whole from there.
The option to view the whole comment is given, if you select a table in a Program window, do a right click on the table name, select "Describe" and klick the [...] button on the right in the Columns window.
But this should be consistent throughout PLSQL Developer to have the same access level in all cases. Maybe it's an alternative to merge Table window and Columns window functionality to have only one option to access table informations at a single spot in the program with all access options available there.
