Recently I added the ability for users to change the path at which they store their downloads in gPodder, I really wanted to use a filepicker for that but based on the documentation picking a folder is not possible.
Any chance we can have such a thing?
Like these maybe? 
Looks like there’s some “for selecting a file” sentence on the documentation but that smells like copy-paste from the file picker.
Yup, thanks!
I actually googled “sfos silica FolderPickerPage” and got no results 
Actually this solves it mostly, it would still be cool if these pickers also had a property to allow the user to create the folder that they want to use.
A bit more -
Currently the picker allows only to pick existing folders, on “desktop os” when you are choosing a folder for something you can generally create a new folder directly in the folder picking dialog.
This could either be implemented like in @ichthyosaurus File Browser - pull down menu “Create new folder”
Or alternatively at the end of the folder list (/bottom of the screen where there are no more subfolders) there could be a + Add Folder item
To me the second option seems a bit more straightforward to the user.
That’s a fair request, added an internal task for that.
