SUMMARY The Merkuro Mail application is difficult to launch, since it does not appear in the menu. STEPS TO REPRODUCE 1. Install Merkuro Mail from Discover 2. Open the menu and search for Merkuro OBSERVED RESULT The Merkuro calendar and contacts applications are listed in the search results, but not the mail one. EXPECTED RESULT The Merkuro mail application should appear in the search results alongside the calendar and contacts ones. ADDITIONAL INFORMATION The corresponding desktop file for the Merkuro mail app features a `NoDisplay=true` field, which explains why it is hidden from the search results. It looks like it is a deliberate [move](https://invent.kde.org/pim/merkuro/-/commit/77c1dd6d18019498c1293304cb9eb3bfc3e4dd7d) upstream, but I could not find the rationales for it. I fail to understand what's the point of deliberately hiding an app like this. It is properly advertised as beta quality in the description. Hiding it makes collecting valuable user's feedback more difficult. I wish the upstream commit were more explicit about this decision.
Can confirm this behavior on Solus. It's confused our users (and myself) as well. It seems a little odd to allow users to install an application but hide it from the menu.
