[FEATURE] Fast downloading of previously undownloaded posts

[m1n1vv]

We all immediately download files from a favorite post. On mobile devices, this is also possible, but the file names will be a random set of characters. The extension keeps track of which posts have already been downloaded and which have not yet. It would be great if with one button you could download all the files from the posts displayed in your browser.

Let me explain. For example, I have made 40 retweets or likes on my account. To download all these files, I have to scroll down to the 40th post.
Beyond the 40th post, all the files are previously uploaded and they will be ignored. Or if the post is simultaneously retweeted and liked, and was previously downloaded from one of those pages.

This will save a lot of time instead of clicking the download button under each post.
