- no about, no license
- headings for checkboxes and configure buttons: redundancy
- descriptions missing for 'Options'-tab; tooltips are used for the other tabs, but only for the checkboxes, not for the buttons
- 'Revert' tooltip says: 'Restore configuration files backed up before the previous configuration change.' Should be like: '... before this application has been started.'
- no load defaults
- 'Revert' should be located in toolbar
- 'OK'-button is always sensitive, even if there was no change.
