| As long as we are considering options; when adding a layer we could consider a sensible default folder location for the new layer based on any associated "keywords". Probably find the layer that has the most matching keywords and put the new layer next to it?

basically drop it in from the top and let it "sink" until it hits something that stops it.
Consider the following base:
ggppllyyrr
Adding a P ggPppllyyrr
Adding a L ggppLllyyrr
Adding a Y ggppllYyyrr
Adding a R ggppllyyrrR
I also congratulate you on your use of ascii art; it has brightened my day.
For the move up / move down tools we are just fussing with zorder. If move to front and move to back don't make sense kill them as a bad idea.

ggpppplllLllyyyyrrrrr
for g=mapgraphic, p=point, l=line, y=polygon, r=raster. Hitting move to top on the capital L leads to:
ggppppLlllllyyyyrrrrr
That makes sense. But the next two examples are less nice.
1 - ggpplppllLlyyyyrrrr 2 - ggppplllLlyypyyrrrr
Essentially, the described behaviour of moving the L line to the top of the lines breaks down in these cases. There are two ways to look at this, A. move L to be above the first line or B. move L to be below the last point.
1A - ggppLlpplllyyyyrrrr 1B - ggpplppLlllyyyyrrrr
2A - ggpppLllllyypyyrrrr 2B - ggpppllllyypLyyrrrr
I was thinking to do something that doesn't quite meet the description of the tool, and move the layer to the top of it's current, continuous block of like layers:
1 - ggpplppLlllyyyyrrrr 2 - ggpppLllllyypyyrrrr
The downsides of that being the case where the selected layer is the outlier:
before - ggppppllllyyLyyrrrr
after - ggppppllllyyLyyrrrr
...and the difficulty in explaining what is happening in the tool tip.

Correct; that is basically the ordering which allows the "most" content to be visible. So when adding a new layer; it should sift down into the right spot by default.
You are correct that people can mess with the zorder (i.e. drawing order) after the layer has been added; this natural ordering is an application of the uDig Guideline "Sensible default".

Hi Guys, Just wanna clarify some details regarding the ‘natural sorting’ to be implemented on Legend View: 1.
Is the diagram below correct regarding the natural ordering of layers? 2.
Noting that using the Layers View, the user can rearrange the layers anyway they want, irregardless or natural ordering:
§
For example, moving a line layer to the front, do we look for the lowest point layer and move it below this? Or the highest line layer and move it
above this?
§
If the lowest point layer was placed below the lines? Or the highest line layer above the points? <image002.png> Thanks, Naz Chan
