My i3 config: Part four - Picom

So I have a decently interesting looking system right now. At least, according to people that see it. Granted though, most of them do not use Linux, so anything other than a bar with icons underneath a big field of more icons and a trash bin, looks interesting to them.

A big part of the look would undoubtedly be the transparency and the rounded corners. I've written about the window manager I use, which is the i3 window manager. You'd think that's the most important part of the look of my system, but you'd be wrong. Looks-wise i3 only adds the battery notification, clock and system tray at the bottom. Everything else is done by Picom, my compositor. The flavor of Picom I use is a fork of it made by ibhagwan. This version allows the rounded corners and "dual_kawase blur", which I fully use.

My current configuration file I've added below this post, so if you're interested in making your system looking like mine, you could. Most of the configuration is decently self-explanatory, but if you have any questions, feel free to ask me.
