[Qgis-developer] General questions & multiple map canvases

[Radim Blazek]

Hi Martin,

what about stable release? Don you want to skip 0.8?
Could we leave this until 0.8 release? I know that debugging
is boring but there is no other way.

I think that layers (as data sources) should be shared over application.

We should separate layer-data and its symbology maybe?
But what about selection set and query?


Well I don't have capacity to think about this very complex problem
as there are milions of things to do for 0.8, so if you want my
reasonable oppinion wait until 0.8 is out.
