Post tags suggestion

Hello , i recently start to put post and models on this site , i suggestion i would give for tags which is required to post, is either to have the possibilite to have favorite tags ready to use without typing again, or a way to add all / some of the autotags you do on the picutre link to the post tags ? i think the 1st one might be more less ressource consuming

ANd maybe time to time to have a page with a kind of ranking of the tag most to least used ?

Ps does we got some return about our ideas ? or it a surprise when coming back to the site later on ?

thanks in advance for all your great work
