[suggestion] rename/order files after download

[trickino]

I notice that with some hosts, the original names are not preserved, for example with imx.to, so after download they are disoredered. I saw there is an "order images" option, but it applies to all galleries/links, not some of them, and when in fact have an order I tend to prefer the original filenames.
I have a proposal, what do you think of adding an option of renaming files maybe after download ? I see on the context menu of the gallery there is the "Photos" list wiih a column that has the order of each link, so I understand the information is there.

Alternatively this feature can also be achieved if we can execute a shell script that is executed after a successful download.
