Filetype-specific actions on download actions

[VlaDexa]

Describe the solution you'd like

I run lossless optimizers of cover arts for any jpg/png that I download. Currently it is one big command that runs fd over the downloaded directory, searches and modifyes the images, but it looks awful. I would like to request a way to select that I need to run command optipng only on files with png extension.

Additional context

It would be even better if you could somehow match the file type pattern, because some people call their JPEGs as *.jpg, and some do *.jpeg. Both need the same command.

Events

Run command after file download finishes ($ for file path):

some other command

Possible look of this feature integrated into the settings:

File specific actions

Type	Command
png	optipng -o7 $

This suggestion would make a good use of the plugin system.
