Hello,

Just a short video to describe it

looks like the core functionality of pcbnew is not about tracks and segments of track !?

-unable to merge two perfectly aligned segments into one

-leave lots and lots of minuscules segments going nowhere after 'cleanup'

-cannot simplify a string of minuscules segments into one bigger or love to create/stack them

why is this just a 'wish' ?

In this other 'video3' you clearly another problem with the router algorithm.
When the vertical segment is drag to the left, at some point, its the horizontal segment that must grow to intersect properly. Not creating this weirdo triangle.

[Franck78 (fbourdonnec)]

here (video4) the 'Z' is unwanted.

The drag should transition to what is excepted (eg the end part).

To do that you have to drop exactly at one point you segement and get it again.

Maybe a 'pause' can be detected on mouse move and used as a "hey router, try to simplify here".
