N Panel Manager Blender Addon

We all know the N Panel Tab clutter in Blender. The N Panel Manager addon for Blender solves this problem by providing tools to manage addons in Workspace filtering. So instead of long days finetuning Blender, you can do it now in 2 or 3 hours. (151 addons).
Check the link in the description for more info.

Why the N Panel Manager?
How long does it take you to set up Blender when there is a new version or when the startup file is corrupt? For example, I have more than 60 Blender addons, and setting up Blender as I want to have it usually takes more than four days.

Why does it take that long? The N Panel (sidebar) gets unreadable when you enable 20+ addons. We know that there is a solution, and that is to use Workspaces. But this workflow, without the NPanel Manager, has all kinds of quirks:

It's hard to find an addon in the Workspace Filter. First, you have to read a lot of text.
Only the enabled addons are listed in the Workspace Filter.
You cannot filter, sort, and use an advanced search.
Sometimes you don't have any idea what the addon is about.
Often you forget where to find the addon, and you need to look it up in the preferences.

(There is another solution that works with renaming the tabs. But the N Panel Manager works very differently, as we see later.)

The Benefits of the N Panel Manager Addon for Blender
It saves you precious time settings up Blender with all the addons.
The N Panel Manager creates a workable environment every time you use Blender.
Use the addons again you invested in. You probably don't use many of them because the addons are not organized in Blender.
Export setups as presets. For example, you can have a light version and another preset where most addons are enabled. Import them back in.
