I have been on steemit for a while now...more accurate 48 days. In 48 days i voted 1163 times. I know, i know i could have done better.
Source Thank you 
Now why am i talking about this ?
Because i just spent 2 hours trying to find one specific post and i still can't find it (mostly because i forgot the name of the author and the title, even forgot when it was posted) and i am pretty sure i am not the only one trying to find something that we upvoted last month and failing.
Solution?
I need a 
Why do i need a favorite button?!
- Because i would like to have a list of my favorite content regardless of the upvotes i gave.
- So i wont end up trying to find one specific post, for 2 hours. And no, search button is pretty useless this time. Trust me...
- So i wont have to go trough browse history, 34 pages on steemd or the curation rewards list and still couldn't find it.
Why would it be useful ?
As a steemadict, i am used to talking a lot about it, about the content being written and about the authors. Sometimes i need a post that i read in the past, either because i want to give credit to that post for what i am about to say or maybe i need it , to prove a point, or i need a "how to" post and just because i upvoted does not mean i can still find it in less than 2 minutes.
Also it would be useful for later reading...let's say you are in a hurry, you want to read something but you don't have time, so you favorite and read it later. If you still like it, you'll leave it there, if not, you can always un-favorite and move on. Or maybe you are on the phone and you read it and you want to write about it when you get home...you add it to your favorite list and find it again when you'll need it.
Sure, you can say "but you have the "follow" button"! What if i did not followed the author??! Even if i did followed that specific author ...i also follow over 1000 authors, and yes i still consider i am not following enough people.
So as a steemit addict, i would really appreciate a favorite button, for all the content that i would like to revisit.
I know steemit is still new and in beta, and more things will be added, but please, the sooner the better. Thank you!
