Hi, About snapping, when adding new adjacent polygons to an empty area it is
faster to have it another way:
snap to vertices and/or to lines when Shift is pressed, otherwise no snapping.
Perhaps that could be done
selectable. With shortcut run snapping the snap distance can be set to
relatively high value and it is
rather easy to learn where to click so that line snaps where user wants it to
snap and when to press the
shortcut and when not.

This is currently not possible to impose a display order between
features inside a layer.
Maybe it could be done, but in my opinion it would introduce a new layer
of complexity
for something which can be easily worked around.
For now, I would divide my layer into several layers with
Edition>Extract>Create a layer by attribute value
(only my personnal feeling though, as I rarely use OpenJUMP to create
nice maps) > 3. Improve the raster display engine. Larger geotiffs (over 150

Of course, it would be useful. I would create 1 feature request and 1
bug report for that.
Not sure how difficult are these improvements, but I generally lack time
and skill to
progress on raster stuff. Hope other developpers will be interested. Michaël
> Hi Michaël,
Well, I think there should be a display order within a layer based on the
categories set in the
color theming menu (for example based on the labels designated for each
category according to its importance: 1,2,3...).
I know I can divine my layer into several separate layers but in my case I have
a road layer with 7 road
categories. Additionally I will have to duplicate each layer to have nice
double line road patterns.
What I want is to stick with 2 (identical) layers, each layer having the roads
displayed according to their category
importance (main routes on top, local roads to the bottom).
Ok, I will submit the no. 1 and 3 requests plus the bug report.
Thanks,
Andrei
