I have been trying RC3. What a fantastic tool this is.
One bug:
The preview window for the description changes when a user types the description but nothing shows up when pasting text.
In order to see the preview, after pasting I need to edit the description.
One feature request:
It would be nice if the build options were also displayed when choosing "default", or "default for gtk applications". The idea being that one could keep the default options for gtk apps (for example) but add to it, without having to select Custom and writing the whole line of default options.
(incidentally, I suppose kde apps would go into /opt/kde, so maybe a "default for kde apps" option?)
Thank you for the effort of putting this together.
It's great!
