HyperMesh 2024.1 Connector Questions

Hello,
I have some questions listed below that arise from work that I'm doing in the attached .hm file. I'm hopeful that whoever is bold enough to address these questions might be aided by the .hm file.
There are several references to the connector seam quad help page:
- can weld leg lengths be specified (Wh and Wv in Figure 16)?
- how to change alpha (Figure 16)?
3. How to specify mesh density for HAZ components? This example has a 1" HAZ and a 0.375" mesh density
4. angled weld cap - my attempt at creating a rounded or angled cap can be seen below and in the attached .hm file. How do I achieve the cap angle and not a sharp corner?
5. mesh quality in angled surfaces - are there some settings that control the generation of these overlapped and/or poor quality elements in a transition region (the brown plate has a shallow bend at this location)?
6. What's the difference between "vertical" and "vertical (edge)"? Can you provide a definition of "edge" and "horizontal" in terms of the weld shape in the connector control?
7. Edge treatment - for this Seam Quad line connector, I'd like there to be no overlap between the vertical elements generated through the line connector and the base vertical component (brown transparent part). Both "keep" and "cut" result in overlapping elements, and the "treatment" option results in a failed connector.
8. flip angle direction - is there any way to change the direction of the single angled line connector realization within the connector control? I can do it by changing the normals of the shell before realization, but I'd like to know if this is a connector controllable option.
other side:
Thanks!
