[SUGGESTION] An option to select all

[Archilyte]

Lets say for example, I want to get rid of all the post I have saved that belongs to a subreddit. Right now the only way to do this is to manually click "unsave" on every post I've saved... which can get tedious if someone has hundreds of posts saved...

So a select all option would be nice to have in these situations.. It could also be used for exporting a csv, where it only exports the ones you selected.

Also after selecting all you should also be able to unselect some posts that you want to keep for example.
