Version 2.4.0 of GrandPerspective has just been released.
It features a new Control panel, which replaces the old drawer which has been deprecated by Apple and did not fully support Dark Mode.
The new panel reduces screen clutter as it is shared by all views and can be placed where you want.
This new version also includes a fix for an issue that could cause crashes when scanning data volumes.
You can download this version as usual from Sourceforge. More information about GrandPerspective can be found at the project's homepage.
