About Flow Connect:

i dont know how you would build something like that, it doesnt seem so easy...

starting from a selected edge ring, the Connect command just creates a flat edge loop
by inserting a vertex at midpoint of each (selected) edge,
but without moving each vertex along its normal to keep the surface tension, the flow between anterior/posterior elements.

maybe a place to put this would be under Edge|Connect command:
LMB click = Connect as it is already known.
RMB drag = Flow Connect (during RMB dragging, the user would be able to setup the "tension")

PS: do you still remember a scorpius tool release by which the user could
right Alt + LMB click = select an edge loop
right Alt + RMB click = select an edge ring
?
Very curious to me that right Alt key can be associate to other functions, avoiding Tweak keys conflicts.
So, this cant this be useful to create a new Connect function, by which, starting from an already selected edge ring, the user could interactively:
(a) connect an edge loop
(b) slide it to the wanted place (by LMB dragging)
(c) setup its tension/flow (by RMB dragging)?

Just ideas...

Thanks for your attention and great work, optigon.


EDIT:
I cant avoid to imagine an aditional option to Slide command so that
the user select an edge ring, connect, call Slide and
LMB drag = position the edge loop
RMB drag = flow it according anterior/posterior edge loops

Nice to see it wouldnt be so hard to code this!
If you would do this, where do you intend to put the new tool? As a Connect variant (lets say, rmb)?
If so, wouldnt it be possible to set (after call Connect rmb)
left mouse drag to slide the new edge loop
and right mouse drag to flow it (increase/decrease the tension factor)?
tks for the attention, optigon.

About "dot ring":
as Graphite Tool, Dot Ring "just" makes sense to
grow/shrink edge ring/loop discontinuously (select one, keep the next unselected, select another one etc)
so that the user could then use standard select edge loop/select edge ring
and finally delete them and simplify all the mesh (or mesh regions).

"Just" a way to speed up this process of clean up the model,
especially at very dense meshes.

So, this would be very useful, but

have you already think about a tool to select patterns on the object surface?

This would be very hard to code, no?

EDIT:
If my memory doesnt fault, ggaliens plugin has a tool to do this,
but i just remember when i tested it
that it wasnt very simple to operate,
especially because you should stablish the distance between the patterns
and this step wasnt very interactive ...

I've just installed it to test and it is really a powerful code you did.
Therefore there are some many steps to reach the desired result (indicate the edge direction, type values and, if the user wants to Dissolve the edges, remove edge direction parameters).
I think this is the most closest tool i've already seen to allow Wings3D work with patterns.

But, to be sincere, Dot Ring is a simplest idea.
Beyond the standard Grow/Shrink edge loops/rings (Alt+L, Ctrl+Alt+L, Alt+G, Ctrl+Alt+G),
what i would like to see is just a way to continue working with those tools, but growing/shrinking alternated edges,
so that i could then call the complete edge loops to Dissolve them.

Your tool are great, and it would be greater if they could be more interactive and direct, even if to do this you should simplify them.

Thanks for your attention, ggaliens.

Directed edges must be "removed" to then the user .Dissolve. them.

off topic:
maybe we could open another thread to treat this: i would like to ask you some points about Shape Extruder...
