I'm still thinking about this, opened to gather feedback mostly.
Pros:

• Allows to do stuff like "Reset all layout modes", "Set layout for all folders", etc..
  These right know would require walking the HDD
• Don't leave traces when app is uninstalled

Cons:

• Reinstalling without exporting settings results in loss of layout prefs

Details of Changes
Add details of changes here.

• Store layout preferences in database instead of ADS of the folder
• Renaming or moving a folder preserves the layout mode
• No user-facing changes in functionality

Validation
How did you test these changes?

• Built and ran the app

Thanks for the feedback. Could you confirm whether main behaves differently?

No, you are right, It have the same behaviour, so it's unrelated to this PR.

I much prefer the database way as well, because with the system as it currently stands it litters the folders a little too much and I have to put exceptions for my backups and for some other sync/file transfers, or when copying normally from explorer to say, an USB drive they get unhidden and are a pain.

You say there's an implementation to "set layout to all folders" I think it could be done a little like explorer does, if a folder mostly contains images it automatically selects that category for it and uses the layout you hasve set for that category to display it.

Or at least be able to set a certain view for a folder AND all its subfolders.

@Laesx this is how the adaptive layout works but there is another option to turn off adaptive layout and to apply the same layout no matter what the contents are.
