-I observe that without plugin support, blender doesn’t default come with
an in place edge length length adjuster. It also doesn’t have a dual
edge touching angle adjustment tool either.
-The plugin I use doesn’t select and detect the previous angle
or length either.
-Is this going to be a change for the next stable release?
The page Richard linked to shows the things being worked on for the next release:
If you can’t find a “distance and angle tool” mentioned, there will most likely be none soon.
