Hi, today I saw that now snaps are ordered by category on this page http://snapcraft.io/store
My question is: How I can set a category to my own snap?
Currently it’s a manual process which the snap advocacy team have been doing. We haven’t completely categorised all the apps in the store yet, but it’s on our radar to do soon, as a one-off exercise.
Medium term we’d like developers to be able to set the category for their application via the store dashboard. We don’t have a firm date for when that will happen, but it’s certainly a desire to do that soon.
Shouldn’t this be derived from the desktop entry’s Category key’s value?
Not every snap is a desktop app, so don’t necessarily have a .desktop file 
Also, some of the categories in the freedesktop spec aren’t super relevant these days. We’re reviewing the list of store sections to map out what sections in 2018 and beyond might look like.
The reviewed list of snap categories is available in https://snapcraft.io/store:
art-and-design books-and-reference development devices-and-iot education entertainment featured finance games health-and-fitness music-and-audio news-and-weather personalisation photo-and-video productivity science security server-and-cloud social utilities
Publishers can self-assign categories for their snaps by accessing the corresponding ‘Listing’ page ( https://snapcraft.io/${NAME}/listing).
Does the featured flag convey any benefits?
Featured is a special case, and is what drives the top position in GNOME Software (assuming the snap plugin is installed) and the top of the web UI for the Snap Store. I don’t believe the store should allow developers to self-select featured.
