I want to select from a directory only e,CSV .g. nd JSON files using FileSelectionDialog. How can I limit the display of only the files with specified extensions?

@AndriesSHP Unfortunately it actually not possible, but we can adjust it to make it possible. This period I am a bit busy, but it is a feature that I will implement in a near future. ;-)
