In Windows - and who knows, OSX & Linux as well, haven’t looked - you can do something to streamline the process of loading and saving presets.
When you navigate to (for example) C:\Users\Kent Williams\Documents\Rack you can open the context menu (right click) on the presets folder, and click “Pin to Quick Access”
Now when you twant to load a preset, you can just click the pinned ‘presets’ in the Quick Access menu.
The catch is that when you then go to save your Rack patch, the file dialog will bring up your presets folder and you have to navigate back to the directory where you want to save a patch. But often your patch directory will be on the left in the Quick Access menu because Windows remembers your most recently used folders.
