Some of these suggestions are now done in Editor E7, including the new line guide as described.
Also a step towards being able to transfer selected triangles between subobjects. You can now merge a subobject into another subobject. So you could break off triangles from one subobject, into a temporary subobject, then merge that one into another subobject. I realise that sounds laborious but in some situations it could be more convenient than merging everything back to main object and breaking off again. Also, the eventual function to transfer triangles might well use an intermediate subobject invisibly, using this new function as part of the operation.
So I think it's an important new function and seems to work well as far as I have tested, but would like to hear if it works as expected for you.
Editor Patch E7:
Drag selection box:
Function to make drag box from points now available in points mode
Scale / rotate / shear axes are now hidden while making a drag box
Grey button shows drag info to avoid left buttons moving around
Typing individual values to align points:
ALT + click r/f/u numbers to set all selected points to same value
- relative values compared with last selected point not preserved
New modeller line guide:
Set up a trace then click "guide" to create a line guide
- the guide is visible in most editor modes and all views
- options to hide/show the guide or draw it open/closed
Merging subobjects:
You can now merge a subobject fully into another subobject
- this is a step towards moving a selection between subobjects
- triangles can now be transferred via an intermediate subobject
