Don't only support hardcorded /usr/share/applications

[hphilm]

It would be great to support $XDG_DATA_DIRS and/or /etc/xdg/applications-blacklistrc

[Applications]
blacklist=cuttlefish,org.kde.plasma.themeexplorer,org.kde.klipper

This way you can create either desktop files with hide request or simply blacklist applications to be shown on the launcher, similar as we do in plasma-mobile.

Thanks for submitting this issue! I think we'll support hinding applications in the future.
