Application launchers gnome do
Gnome-do seems to be the best application launcher. Theres also kupfer but I didnt like it.
Q: how to make GD find my custom applications?
A: GD finds the *.desktop files stored in so called XDG dirs (info). But briefly: create a *.desktop file (simple text file) for your launcher and put it into $XDG_DATA_HOME ( $HOME/.local/share if the variable is not set)
Q: where is Gnome-do preferences?
A: pop up GD, click a small arrow in top-right corner.
Q: Gnome-do doesnt show some of the desktop files, but Im sure they are present in proper dirs.
A: check if the desktop file has NoDisplay=true. If it does - remove it. Can be caused by hiding an application launcher in main menu editor.
Q: How to calculate with GD? Gcalculate plugin is not working.
A: No solution so far. If you absolutely need it - use kupfer instead of GD
