Yo! This plugin works to diversify your shit code with any pictures.
This is the plugin for JetBrains Products based on the Nyan Progress Bar by Dmitry Batkovitch and Mario Progress Bar by Kylian Meulin. It shows various Progress bars and allows you to customize the loader yourself in settings. (But the picture or gif should be 20 pixels height ...)
You can install YoPlugin from the JetBrains Plugin Repository, directly available in the IDE preferences.
File -> Settings -> Tools -> YoPlugin Settings
Chose image or gif file -> Click on Custom
At the moment, changing the size of the icon is not implemented. The current solution broke the gif animation. So, if someone suggests a solution, I will be grateful.
