Less complex tool to project a point(s) on way segment (current tools are not predictable)

[openstreetmap.org-user-d1g]

I was asking "project a node at user-defined segment" for year(s) at forums, but it is still unimplemented in JOSM (closest solution is still to use angle snapping to selected segment, then remove temporary geometry, then merge nodes - but this is too many steps). Other possible solutions are also lengthy: ​1

Current "automatic projection" of all nodes to all "faces" doesn't work as user would like. But the worst thing there no alternative other than AS mode.

"how to control this thing":

Here I got 4 correct, 2 okay results, one error and one WTF result:

... and if you think GIFs are fake

Here is less complex scenario or explanation why you need to project a node onto way/segment: ​http://forum.openstreetmap.org/viewtopic.php?pid=350899#p350899

There many short roads/footways that lead to entrance=*s.

You want a tool to connect newly drawn entrances to the rest of the graph. You don't want them to look ugly. Community agreement is to make "straight"/nice angles whatever possible with roads.
