Hey P3aul,
I am frustrated as well.
I don't feel competent to do my own 'Makes' unless the instructions are precise.
Which is the problem. the target keeps moving with every distro upgrade

and the developers would have to spend time working on the various instructions (over their own platforms build)
For now, I run Sigil on the Windows side of the world.. Even that has problems with tool changes (5.902 won't save the main screen location for full screen on a multi-head system. works OK for reduced size)
