Hi Markus,
	I’ll make sure to include it in the ChimeraX implementation when I get there.  To get ChimeraX where it needs to go I can’t put too much work into the current Chimera but nonetheless I added a “lineType” option to the hbonds/findhbonds command so that at least in the command version you can get dashed H-bonds without code modifications.  The valid options for the lineType are:  solid, dashed, dotted, dash-dot, and dash-dot-dot.  The option will be available in the next daily build.
