Do you mean add support for more browsers in the 'Webgames' feature? We're going to replace that in the near future with a feature that will record all or part of the screen, so its more widely useful.
Ok, noted. A few of you have requested the ability to record MSI Afterburner with FBX, but this is tricky - Afterburner adds its overlay after FBX gets its snapshot of the game image.
We've had a few requests for different audio sources to be saved into separate tracks to make editing easier so it is on our list of things to take a look at. Not sure when we will get to it though as we've got a few high priority items that we want to focus on.
We do intend to add options for applying various effects whilst recording but they are still some ways off in the future. Not sure if zooming is going to be part of that or not. Zooming whilst editing is probably more likely.
Adding meme sounds is a little tricky because there can be copyright issues with a lot of them. For now we'll just have to leave it to users to find the sounds themselves at places like soundboard.com and import them into FBX at their own risk.
We've not changed anything relating to video quality in version 3. If you set "Medium" for Quality, this should set the quality and vary the bitrate to get that. The bitrate will depend on the frames per second and dimensions of the recording.
Go to Settings -> Audio and make sure you have 'System sounds' selected, or you might not capture their chat correctly. If System Sounds is selected, then FBX should capture it at the same volume as you hear it when playing.
