also I would love a “half-manual” mode where you can specify the domains and all their webroots (and optionally cert/key paths) you want to get for a cert, that way I could get the whole setup from my network (I have my network paths to my PC to the webroots [and other stuff] always ready) that would give people no matter what server they use the ability to use the tool.
for example you could read a file which has line seperated:
and it tries to make one cert for all unless a line with only a - appears, that could be a SAN break.
