I need to add UI stuff to use `winget configure` and `winget download`.

[DrewNaylor]

For winget download, I can have an option that specifies where the installer goes if that's an available command line, along with a button to open the folder. It could be a thing in the config file though, so I'd have to pass and retrieve it via winget settings when the user changes it in the UI or wants to open the folder.

winget configure can be under Tools probably, or maybe file. It should be "Load winget configuration..." I think. There would also be "Save winget configuration...". Probably should give the first one Ctrl+O and the second one Ctrl+S, or maybe something else less likely to be used.
