v5.2.0

Fixed a major bug where some windows became transient after being created preventing application data to save properly on close.
Example: Firefox extension windows sometimes become transient.

Added setting to only write save file on shutdown, while less reliable, this might prevent lag issues for HDD users. Use this if you use a HDD as your /home drive and experience lag when closing apps.
Added firefox to default whitelist and perfect restore list (different package name on arch based distributions).
