[OpenLayers-Dev] new OpenLayers map viewer with custom components I´d like to share

[Roald de Wit]

Hi Juan,

Thank you for sharing the work you've done based on OpenLayers. You will
find that it is easier for your contributions to be added to OpenLayers
when you break them up in smaller bits. You can then create a ticket and
a patch for them [1], so they can be reviewed separately.

If you have found bugs in OL, please report them so they can fixed in
the main application as well. Things like controls not having id's or
classes can be bugs.

You seem to have implemented a new layerswitcher. If so, this could be a
candidate for an addin [2], since it is new functionality that is not
part of the core of OL, but could be useful for others.

I hope you can/will make the time for reporting the bugs you've found
(and the new features you've created). By doing this you'll help making
OL even better than it is now!

Regards,

Roald
