Im with you.
The "like" symbol finally appeared two days ago. I stil don't see any way to edit posts or quote all or parts of other posts. I don't see anyway to add emoticons that others have mentioned.
There's too much empty space as viewed on my laptop. Three single-line posts take up my entire screen. The font looks lighter and bigger than before(?). The new format seems less engaging. Maybe with time I'll get used to it.
