Almost 3 years, I started off modding minecraft. (I made really stupid mods) After I got used to java, I started making my own little programs. Most of the UI on connect was designed in photoshop, which I have been using for about 4-5 years. Thanks for the comment 
I probably will make a setting where you can choose between a light and dark theme
Would be nice with a release, Any chance?
A release of? ???
Of what you’ve taken the screenshots from.
Since the jframe is undecorated and has sharp edges, i just use the print screen button on my keyboard and crop out the background in photoshop
