Hi,
+1 for renaming current snapping behaviour to "Layer Units" AND adding a
global snapping-unit option, _perhaps_ as default option.
You very often want to snap in linear units regardless of layer CRS, so
a possibility for doing that globally would be good.
Maybe if this option is chosen, it calls a subroutine to convert this
linear unit into "Layer Units" and populates the "Snapping and
Digitising Option" table for the user, in the layer units.

Hi
Recently I have been working on some snapping improvements (more about
that later) and I have found one slightly surprising thing about the
configuration of tolerances: if the tolerance unit is set to "map
units", it actually means "layer units" - i.e. units in layer's CRS
and not in project's CRS. Recently there was even a bug report filed
for that: https://hub.qgis.org/issues/11634
I would like to change the behavior so that the "map units" in
snapping config dialog would mean units in project's CRS. Would there
be any objections?
Alternatively we could just rename "map units" to "layer units" to
make it less surprising (and eventually add a third option to use
project's units).
Cheers
Martin
