[Option] Set width manually / store tab width

[Cardridge]

Looking up the issue tracker, this same subject has been brought up by https://github.com/traxium/tabtree/issues/14 already. It doesn't seem to work anymore. Is it possible to just give another option to manually set the default width to work around this issue?

Use Stylish:

#tt {
    min-width: 300px;
    max-width: 300px;
  }

Just change 300 to whatever you want.

I guess this works as well with userChrome.css. It would still be nice if the selected width would be stored by the addon.
