COSMIC Store is coming along quickly, though there is still a lot left to do. It loads nearly instantly, because it uses bitcode to cache appstream data in an optimized format. It uses very little memory compared to the Pop Shop. Searches can be performed live as they are done in parallel. Searching for "e" takes 5.5 ms on my desktop and returns 4601 results.
Wow, that's really fast for an application store! On a completely unrelated note, will it be possible, or rather could it be considered to add the ability to change the emoji font in the settings as currently there really is no quick and easy way to do that on linux.
