Those duplicates that were deleted had been caused by bad timing of attempted posting (forum in midst of its nightly fail). Multiple attempts to post without recognizing success, then the one 10 hours later was the only one known to be completely submitted.. but it too was in excess.
Anyhow. New news, I may be looking into some small amount of "using the Xenforo online style configurator" to set some values but given the wackadoo way that the color variables got used within the theme, I do not plan to include those (at least not at present or the near future). I am also considering moving various details of my EXTRA.css in the Experimental 'parent' theme into the various dozens of constituent css files. This should help allieviate the vast use of !important; on each line of css that are my adjustments.
I remain interested in helping the Experimental Ganz großes Kino theme become a complete departure from the bulk of its origin(s) but if this might include file name changes, that is something I must investigate further. I need to better understand how everything fits together, know which bits are part of any default/base Xenforo thing(s), and eventually develop any needed scripts/techniques of my own. The closer I get to Experimental having all of its many details perfected, the sooner it will be renamed (has been, any Experimental theme that may exist now relates to following) and set out as a theme unlikely to be modified further. Then, as a starting point I can use a duplicate of the parent along with any of the hue files to create my departure theme. When the departure theme gets stable enough, I may allow it to be selected but at that point it would be called 'Experimental' with its perceived potential for change/breakage by its very name.
UPDATE:
I still need to work on making all of the various color choices (greys primarily) consistent across the entire theme. I like how the forum category list looks, and hope to duplicate this. Then along with this consistency, I want to at least clean up the css once more. I may either convert my choices of selector to those that had already been used by the original theme stuff, or use my version of selector and remove the original theme stuff.. or a combination (most likely). Some of the conflicts and difficulties I have relate to attempting to reference any onscreen entity by way of a selector, but sometimes the original selector somehow pinpoints the entity more easily than I can determine by way of the in-browser "Inspect Element" tool. There are a few places that use graphical icons instead of fontawesome alternates which need changing. The star ratings were a challenge last time I tried replacing those, I hope to succeed eventually.
Did I already mention my interest to make these forums lynx-friendly? I am not sure how easy it would be to adapt the present structure that our current Experimental Ganz großes Kino theme uses, but it will likely be less work to redesign from scratch, such as the planned 'departure' theme. Ultimate names of each have not been pondered, not even vague ideas for names as yet.. a name is much less important than what it references. :)
