Feature request: add snapshot of stash space

[ypad]

It will be great to see what the bot have collected from time to time without interrupting the bot. I wonder if it's possible to take snapshot of the stash space (which every tab the bot opened) every time the bot visit stash, and update this picture to a file. In the UI--very much like the button optimize and show--I can click a button "show latest stash", and it will show the 4 stash tabs side by side from left to right, so that I can have a good view of what the bot have collected so far.

This is very useful for people farming for a certain item/set items/keys. This way they know when to stop, or change shard spending method, etc. without stopping the bot and go check the stash.
