Large variable settings

Tabtamer seems to like to store a lot of things in its variable that are not real overrides. I have a tabtamer variable of size 24k. This is a performance concern.

select name, length(value) from variable order by length(value) desc limit 0,1;
+-----------------------+---------------+
| name | length(value) |
+-----------------------+---------------+
| tabtamer_tab_settings | 24720 |
+-----------------------+---------------+
