I'm so glad that you bring this back to the communities attention because I think about this EVERYDAY and even wrote a post on it sometime during the ending of last year 0r beginning of this year.
It get's pretty cluttered when having your personal post along with resteems added together. I absolutely agree that we definitely need better organization to this matter!
I like your tab idea but would suggest simply using 'RESTEEM' as the the tab(name) rather than 'SHARE' ;)
But yes, we need a seperate tab, come on STEEMIT! It's been a long time coming! I 0r WE would like to see this feature come time during the next hard fork.
REsteemd lol
Thx you @jerrybanfield
Resteem tab sounds good to me! Thank you for letting me know this was already brought up before which with repeated suggestions we might get some action on!
