[Pharo-users] changing theme colors of windows without closing them

Hi, I fairly often switch themes (sometimes daily), and the fact that windows don't properly switch is quite annoying as I have to close literally everything and start over. Is there a way to force-reload the colors without closing the windows? For Nautilus I could probably script something like this (NautilusUI allInstances select: [ :each | each window owner = World ]) do: [ :each | |new| new := each fullBrowse. new ui window position: each window position. each close. ]. both for the rest (GTInspector in particular) I cannot just close them because I have live data there. Thanks, Peter
