How to make a theme for LMMS

Write guides and how-tos about LMMS for other members.
There are many ways you can make a theme in LMMS, but the easiest is to use the icons already provided in the default theme. To find the default theme you have to go to Computer>usr>share>lmms>themes>default, or just search for any of these folders in the computer folder. After that you can copy the default folder and paste it in another location. You cannot paste it there as access is restricted, so you will have to paste it into a different folder and rename it. You will have to go to the LMMS settings and select the newly pasted folder as the artwork folder. Then you can go through the contents of the new folder and change the parameters (hue, saturation, etc. ) of the pictures. To do this you will have to have a simple image editor that can also be used as a gallery. Changing all the pictures in the same editor and with the same parameters will result a nearly monochromatic. After you have changed the pictures you can edit the css file named "style.css" to change colors and much more. Make sure to not change the names of the variables, because after that they will have to be changed in the main program and will not work on any other than your own version of lmms. The same goes for the names of the pictures in general.
Could be possible for us to known where every image in Computer>usr>share>lmms>themes>default is located in the program UI?
