I got now many demands from players for wanting to have especially replays in lobby as option. Also the last summary from a game should be available as option in lobby. Therefore the buttons below chat input are told to look appealing from players (@mapkoc, @Hannibal_Barca and more). So also having a button for options (changing settings in general and for lobby ofc) and for looking up history or civilization's info as button should be good (also if you want to talk about these things too).
Also go into replay without leaving lobby should be possible in conjunction with lobby overlay (D817), so we can look into lobby, while in a replay (not missing anything :) ).
Last Summary is in D854.
More Buttons Bar can be disabled, hidden or always visible. When hidden option is applied, it gets shown, when hovering with the mouse pointer below the chat input.
Buttons bar shows up on pointer hover area on bottom of window
Civs info is actualy hard to see but its opened guiPush from lobby.
Replays menu from lobby opened as dialog.
