Setting up your addoncollection manager is quite simple now since the original Python plug-in has been modified
I will start with the brush manager for this tutorial.
You will need the plug-in that is found
HERE If you are using Linux, make sure you check execute in the permissions allowing executing file as a program.
original doc.
http://gimp-tools.sourceforge.net/managementtools.shtmlPlace this addonCollectionManager-3.0.py into your user Plug-ins folder.
Open your .gimp-2.8 folder, right click inside the folder and click Create folder and name it brushes_storage.
What you need to do now is make several folders inside this storage folder. Here is an example of some of mine. Remember to capitalize the folders.
You can make as many folders as you like and add them later if needed.
Now that this folder ready, go to your brushes folder, cut and paste all your brushes into these folders. This is what takes the time trying to sort them out into the proper folders.
Make sure all the brushes are gone out of your brush folder and into your brushes_storage. When you open your gimp, only the brushes you have selected will show in your brushes. You will be able to tick beside all the brushes you want to open.
When this is done, open your gimp and right click on your brushes and you should see brush sets.
Click the brush sets and another window will open and all your brushes will be in view that you put in the alternate folder, Click beside the brushes you want to open and brush manager will open those and click ok
All your Gimp default brushes will be in with your brushes so you don't have to load them because they will already be there,
TIP... The reason you will be emptying your brushs folder is so that just the brushes you have selected will go there. If you untick those brushes in your brush manager, they will go back to your brush manager and that brush folder will be empty again. So, the only brushes you will see in your brushes folder are the ones you have selected and the default brushes
