If they market towards companies - the search is still very bad, doesn't give any options (like search within a timeframe, search types of attachments etc... compare that to discord or slack e.g.), it's completly missing on mobile.. and generally sucks at showing attachments - seeing something from 3 months ago is incredibly annoying if you have hundreds of attachments, sometimes due to a bug even impossible. Hopefully slide sync and other stuff will adress all this filtering, searching and moving around a timeline quickly (going back a week ago? good luck). Also the amount of bugs as of late is quite worrying - after a year or two I am having issues with encryption all over the place, the notifications were buggy (maybe the version that's not showing up for me in the playstore already fixes that)... so I feel like the resources should be focused towards polishing and not rewriting everything again.
And if gamers and home users are their niche and want to target those users - discord users were asking for custom emotes for years now and while a solution for stickers exist, it's not for emotes.
Also I don't understand why pouring resources into its own videostreaming when jitsi seemed like a very good option already - again in my opinion should've been a low priority and scheduled for much later in the pipeline.
Again I truly hope Matrix succeeds, but making a better experience, useability and polished product should be the focus now. While third party clients may have other features, it's Element that will be used the most by people, at the start at least.
