Allow saving the Guides and Grids configuration
Just as there is a tab that allows us to save Tools Presets, there should be a tab where we could save Guides and Grids positions to be used in any document. In this tab it would be possible to define the name of the saved Guides or Grids configuration.
The tab could be similar to the Tools Presets tab, with an icon for saved Guides and an icon for saved Grids, with the respective name on the front.
It would also be nice to already have some grid settings and guides pre-configured in this window when installing GIMP, such as the rule of thirds.
