[Qgis-developer] Teaching Processing: notes from the wild

Hi all.
Just finished a course on GIS analyses, following mainly the sextante tutorial; here
my notes:

* Random selection: the selection does not appear, as the module is not refreshing
the view
* Split randomly: the % is not exact (e.g. if I select a 20/80 split, I get 22/78 etc.)
* Create graticule from extent: with lines, one of the points (first North-West) is
left out; with polygons it is ok
* In the Log viewer, the button Cancel is misleading, and can lead to loss of
important data a bit too easily; better to give a warning before actually deleting
* the Field calculator is barely usable without a dropdown list of fields and
functions; on win it does not seem to work (most or all calculations end up with all
NULLs); unclear if this is due to minor edit issues from users (quite likely without
the dropdowns)
* it seems impossible to make conditional models (if this value is ... then run this
command, else this other one): am I correct? this would be a major improvement IMHO
* I cannot have OTB running, neither on Debian nor on Win (osgeo4w 32 bit)
* I get a systematic crash when attempting to edit Processing or R scripts, but this
may be a local issue
