I use Connect too and I consider myself as bit of a power user(have 6 clients installed my phone). Connect has all the features or even more than any other client. The horizontal swipe to navigate the posts is my favourite and probably only client that has this feature.
I tried so hard to stick to Florisboard but gboard is waaay too convenient that I keep going back to it. I wish Florisboard at least adds feature to search among emojis.
