I am new to Textmate 2. I have seen few people using textmate with a reduced opacity of the background color. I am trying to find a way to achieve that, but could not get to anything closer.
I tried tweaking the bundle file for the default theme, but eventually ended up messing the look of the existing theme.
What am I missing here. Do I need any other bundle to achieve it? How do I get a transparency in the background?
