I'm looking forward to see such feature!!

Two last questions:
- For the gambas2-gb-db-form package these seem to be the right
dependencies:
 gambas2-gb-db , gambas2-gb-form  gambas2-gb-qt-ext  | gambas2-gb-gtk , is
it right?

- When editing menus, objects properties, etc. the ide always show stock
icons, but if you don't use gb.form, they can not be loaded, so shouldn't
gtk and qt always load gb.form and disable its unload unless gtk or qt are
unloaded?
