<div class="moz-cite-prefix">Hi,<br>
+1 for renaming current snapping behaviour to "Layer Units" AND
adding a global snapping-unit option, <u>perhaps</u> as default
option.<br>
<br>
You very often want to snap in linear units regardless of layer
CRS, so a possibility for doing that globally would be good.<br>
<br>
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.<br>

<div>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: <a
moz-do-not-send="true"
href="https://hub.qgis.org/issues/11634">https://hub.qgis.org/issues/11634</a></div>
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>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).</div>
