[Martin Dobias]

Hi

First of all thanks everyone who contributed to this thread - there
were many interesting ideas that we can discuss further.

We are still looking for funds for the project (so far we have reached
~70% of the goal) - and therefore contributions are welcome!

This is not part of the refactoring work, but it is very interesting
use case and therefore I will keep it in mind and do the design in a
manner that adding such functionality should be possible. Advanced
legend manipulation could be another followup project.

While we have discussed various aspects, we have not reached too many
conclusions :-)

- legend vs layer manager - there was a good point that we are mixing
the concept of map legend and layer manager into one tree. While these
are related, they get into conflicts... while layer manager should be
a tool for management of the map (and be as powerful as possible), map
legend should provide mainly the help for the user to identify the map
elements (and be as simple as possible).

- support for multiple canvases - while it is not the intent to have
this functionality when the refactoring is complete, the work should
bring us a bit closer to that. It is still unclear how multiple
canvases should behave as there are lots of use cases with different
needs, e.g.:
  - tabbed vs split screen canvases
  - same or different map extent
  - same or different layer styles
  - same or different set of layers / visibility

- new functionality suggested - we discussed some of the ideas from
the thread, especially the ones from Olivier. No conclusion was
reached whether to adopt all of them in the future, but the icons as
indicators for labeling, diagrams, snapping, actions, editing(?) etc
were seen as potentially very useful. They could be even used for
reporting map canvas refresh progress (animated wait icon) or
errors/warnings (e.g. reprojection failed).

I am sure there were more things discussed which I have forgotten
already, other participants please feel free to add your impressions.

Martin
