We can always make a request to them in their Github...but I've tended to not put too much energy into that for a long while now.
Not meaning this as a complaint...they'll do and get to the 'features' they want, when they want. So I tend to not get excited to await anything specific, just so I don't get frustrated. I'll honestly be surprised if they put more features into steemit in the foreseeable future...with their major focus being the Smart Media Tokens (and other bigger things that still have to get dealt with like the bandwidth calculations.)
I have at least seen chrome extensions before that did all the things we've mentioned. It's just been a while and I'd have to track them down...on top of I don't know if they still are working.
