hey guys, I would like to customize my conversations too, and I have a few questions:

how do you do, or which program do you use to change edit the html/css/js files?

Do you have any way to visualize them in your computer or is more like a trial and error thing? (I mean: you change something, you put the files back into the phone, you check if it worked as you expected, and then you take them back, edit them again and repeat the process).

Thanks and keep the good work .
