Exit Key Binding, Spectator UI Strafe, and Text

I play on PC/Origin.

I'm not sure why, but the spacebar-to-exit key seems to work when it shouldn't and not when it should. I'd rather not have spacebar be the exit key, but that doesn't have to be a global change to work.

1) I'd love an option to disable it entirely and instead have a GUI button that can be clicked with cursor on it, held for a short time such as the hold time for weapon swap,  and then bring up the exit dialog.

Plenty of times, I will be killed and immediately the exit dialog appears and blocks the screen just because I was about to jump. Other times, spamming the spacebar while dead to get out of the map has no affect and changing spectator tabs or something is required to get it working.

Please allow the player to choose the exit key and add a setting for PC players that can disable spacebar-to-exit and replaces it with a GUI button to exit the match.

2) For PC, it would be great if the strafe keys could move left and right through the top tabs while spectating. Maybe add a setting to allow/disable this.

3) Please add unified party chat. Carry over party chat from lobby to game and game to lobby. Just show the previous lines of text in a different color so there is crossover between these two screens.

There can never be too many settings! Thanks.
