I read today in a
blog post by Niklas Heidloff that IBM has been thinking about of building a converter of custom controls to extension library controls.
I think that isn't any good idea, why because the installation of extension library is
alot of work today why would you like to have even more controls that needs to be installed into the designer and updated individually?
If this should become a good idea, then we need a new way of updating all these controls like the updater in Chrome or Firefox.
And the updater can have several update sites so you can have one on your local domino server for your own controls and one on OpenNTF.org.
