Drecreased precision when adjusting input fields with Shift-Alt-Drag #45280

System Information
Linux Mint 17.1 x64
nVidia GeForce GTX 770 using proprietary driver

Blender Version
Broken: 2.75
Worked: 2.74

Short description of error
When adjusting any input field using Shift+Alt+Drag, the minimum increment now seems to be at least one order of magnitude bigger than it used to be in 2.74. For some fields, like the object location, the precision seems to be the same as before, but some other fields have changed dramatically. (Also, the 3D cursor location fields are using a different precision than the object location fields.)
One instance where this is not only extremely noticable but also kinda breaks a feature for me is when trying to precisely adjust a background image, because the size field will now only work on two digits of precision, but it used to work on three digits in the last version.
This becomes even more extreme when working in metric units, because at scale 1.0 the minimum increment is now 10cm, which is completely unworkable. It used to work on 0.001 level, independently of the unit system.

Exact steps for others to reproduce the error

open Blender
add a background image to your scene
adjust the background image size with Shift+Alt+Left-Mouse-Dragging
notice the increment of 0.01 when using Blender units, 0.1 when using metric units.

Campbell, iirc you removed that shift-alt-drag precision feature when you added "multi-edit" one?

This was an intentional change.

Using Alt+Shift no longer works for extra precise snapping.
Its in conflict with multi-value editing which can also use shift+drag for precise editing.

Thank you for clarifying.
I never had use for multi-value editing. However, ultra-precise snapping was an important part of my workflow and now that it's gone, I cannot adjust background images anymore.

Even if I might get ignored, I still want you to consider that this intentional change utterly destroys the ability to work precisely with metric units. Remember, the smallest possible increment is now 10cm. Besides, this change has introduced inconsistencies in precision handling, depending on the unit system. Adjusting numbers using Blender units is now 10x more precise than using metric units. :-(

Instead of just whining around, here's a suggestion:
Can't this feature be restored by making it assignable to a custom key combination?
