I'm using the new canvas. The migration becomes ok when you find all the
equivalent ways to render stuff.

I never use decoration nor #isolate: (yet) but I think about that feature
that it could be handly and perhaps I'll be using it soon.

I'm using dialogs a lot. I'm developing almos the same as desktop and
dialogs is something we need. I'm using one or two kind of modeled dialogs
wich render a customized frame so you can put there any component to be
rendered but letting the user the clasic cancel ok (#save #rollback)
features. I think this is a must.

I'm also using them a little. They are handy to find a component class and
sometimes to inspect something.

I don't needed it yet. Just configuring custom session libraries, etc.

We haven't go that deep yet.

They are a must too. I must admit that I've completely understood them

We rather use them to call the dialogs wich mostly are to edit some object

I'm not using effects yet. We found of more value the updater, autocompleter
and the editor.
We use and reuse shore components quite often.
