[Feature Request] Remember 'Search Term' or 'Collection' When Searching Again

[luxlogica]

Currently, when searching for images by a specific search term, or when using a collection, the process is cumbersome - specially if we aren't happy with the first image found, and want the plugin to fetch another. What makes the process cumbersome is:

1. There is no keyboard shortcut for 'Fill Based on a Search Term', nor for 'Fill from a Selection' - so we have to go to the plugin menu, and navigate
2. The plugin remembers the very last search term or collection entered. But if I'm not happy with 3 or 4 images, and they all require different search terms, I have to click on each one individually, and try re-searching with each one at a time.

What would be ideal is for us to be able to 'store' the search terms or collection id along with the layer - e.g., in the layer name - and then for the plugin to use these (if available) when searching again.

Other plugins - e.g., Paddy, Easing Gradients - store the information they need to use within the layer name. I'd suggest that Unsplasher could use something like this for normal search terms:

Rectangle {face, woman}

...and perhaps something like this for collections:

Rectangle {c: 332024}
