I have 2 little problems with ElvUI. I hope you can help me find solutions.
First one: is there a possibility to make chat font bigger? I can't find option responsible for that.
2nd: i'd like to make player frame looks more like this one in XPearl. Mana and hp bars are for me not visible enough so far...
