Feature Request: Further options for dealing with duplicates

[IdrisQe]

Currently as far as I can tell the only way to deal with duplicates is to click the "Sell" button which, as fas as I know (Too scared to try it currently), sells all but 1 of each duplicate unstackable item?

It would be nice to get further control over this behaviour, such as an amount box where you could specify a number of items to keep instead of just 1 (in case a lot of weapons are used in multiple future recipes for example), or a button to only sell items that are not listed as "Material" in their tooltip.

Also, not sure if this works presently, but it would be nice if you could manually sell items 1 by 1 by Control-Clicking them in the menu like you do when selling to NPCs. Currently it makes a "Trash" cursor icon but doesn't actually do anything with them (though we have deletion-selling disabled currently, so I'm not sure if this behavior is already implemented?)
