Update themes to sa-1.1 / ttkthemes-3.3.0
Thanks for the bug report
German update.
The file to edit is scid.gui
I don't know why this restriction is in place, and have removed it. You may either checkouut subversion and recompile, or remove these lines from the gui / tcl/utils/win.tcl if {$tree_count > 1} { tk_messageBox -title Scid -icon question -type ok -message "Cannot save layout with multiple Trees." return 0 } Which will work, but doesn't have the full error checks i added to svn. https://sourceforge.net/p/scidvspc/code/3655/
Allow multiple tree windows in saved layouts.
Options->Save Layout Options->Save Bases as default But hmm, i'll have a look at that multiple trees error.
Saving multiple tree and window layouts as default (6 or 7)
