As far as I know and as I experimented with MM 20.3:
- there are just 2 LAF delivered by PTC:
-Dswing.defaultlaf=com.osm.ui.laf.xplookandfeel.XPLookAndFeel: this one looks like the former one, but it does not implement the quick access tool bar and the quick search. The same LAF didn't in 20.1.
-Dswing.defaultlaf=com.osm.ui.laf.ptc.PtcLaf: the default one. It implements the quick access tool bar and the quick search, but does not look like the former one for some details.
Alternatively you may use some other LAF delivered in your java SDK
