Default How to fid "non-manifold" an "open edges" objects

Hi all,
I am using AC3D for more than 10 years, but still have trouble with AC3D object "consistency" related to boolean oerations and now, when I fall into 3D print world, also with related "non-manifold" objects.

I feel quite big AC3D insufficiency regarding some letīs say object checking or help to identify problematic places. When complexity of builded object increases, mostly I get to the moment, when I am not able to do boolean operation duet to "open edges" and I am not able to find where the mistake is. Mostly these inconsistences also results in not printable objects as slicer software reports "non-manifold" object.

So, my first question is, it is there any way in AC3D to identify and fix these things without using some other software, which I must such object import in and do check and fix? (for example Blender has this option)

I know that there can be several reasons that object is not manifold (and much of them probably means also inappropriate for bolean in AC3D) - for example self intersecting object, separate innner object, holes, inner "T" faces, overlaping geometry ... and so on. Anyway, when AC3D is able to identify some of them, why is not able at least to show, where they are to be possible to fix it manually?

And second question ... if answer to first question is "not at this time", is there any possibilty have this feature in the future in AC3D? (It is probably question for Andy or his colleagues...)

I will be glad for any advice from local experienced modellers.

Regards,
Lumptom
