Hi,

I think I said I would try to move this discussion to the dev list; not sure if 
that is the right method but here we go anyway.

The basic comments appear to be summarised as follows:

-> I have noticed that some of our layers are very slow loading in the layer 
preview and I would usually switch it straight to cache mode. On this basis and 
in discussion with Ian T we raised the ticket 8413 to suggest that tiled 
'might' be a preferable starting situation.
-> Andrea noted that in some cases it is preferable to use single tiles due to 
labelling etc. Suggested a configuration option instead of default?
-> Jukka noted that the default map window is 768x330 so the single tile 
request may not actually be that much different
-> Andrea noted that the default tiled map is 3x3 which is actually an area of 
768x768 in reality.

So in terms of the comments I do take the point that the area requested may be 
actually smaller in terms of the data behind the scenes but I had primarily 
raised the issue on the basis if the general feeling when using the layer 
preview. In my view the point of tiling is primarily to ensure that the user 
can see the data loading rather than waiting for the single render. I do accept 
the points raised but I do still feel there may be some benefit in allow the 
user to decide.

I think Andrea was indicating that the tiles may not actually come from the 
tile cache but my understanding is that this would be the case if you open the 
links via the Tile Layers screen.

Primarily I had added this one as I hoped it might be something very simple 
that I could look at whilst I'm learning to be a contributing developer but of 
course I will be guided by your views.

Could we just add an extra option to the dropdown list as OpenLayers is already 
duplicated in that list?

The proposal would simply be to add OpenLayers (Tiled) as an option in the UI.

Cheers,
Paul
