Editable and Organizable Snippets?

I see there is a "Snippet" list underneath the "Library Filters" flyout in the browser - obviously those being the snippets that I've downloaded, but none of my snippets are listed under "Custom Filters", or anywhere else in the browser. I have no way of accessing or organizing my bank of snippets without creating a temporary filter. To say nothing of the inability to place them into any kind of folders...
Can we have a way to browse and organize our own snippets?

At present, the only way that I know that one can edit an existing snippet that you have saved is to create a new filter, create the snippet, ungroup it, make the tweaks that you want, delete the old snippet from the component list, and then create a new snippet (ostensibly with the same name).
Could there be an easier way to edit an existing snippet preset?
