I almost forgot.
In answer to:
"3-Do you know if there's any plans to add the option to export games to be played in the browser in future versions?"
There are some websites(usually Japanese) which you can upload your WRPGE game to and play the game on the browser via a player. I don't know if there are any special specifications or settings, but I am informing you that one can indeed play a WRPGE game via a browser.
I hope the information I give you helps.
Good Luck, Take Care, and God Bless.
