alpha 2 to 5 have mostly been PHP fixes and work, little to no work has went on on the front end so the things that were broken in the first alpha, remain broken in this alpha. One of the new front end features i've been wanting to bring to babble for awhile, is instead of fixed heights for everything, i wanted dynamic heights for it. so it will responsd to the view port size (well, it will measure from the top of babble itself to the bottom of the view port, and resize everything to 70% of the height of that area, hopefully avoid scroll bars and what not. the chat message area has a min height of 150px, cause i just know there will be one person out there that be on one of those 3 inch cheap af android smartphones from back in 2011 that has resolution of a calculator ).
I've also been getting a huge amount of feedback from the IPS forums, mainly cyboman, who has given me a ton of great ideas on how to improve bots and other features in Babble. so like always if you have a suggestion, this is the best time to make it
