First let me apologize for asking without properly evaluating first. I took some time and read about Nautilus which it seems a very nice work. I&#39;ve developed a phylogenetics classifier using OmniBrowser, but I wondered if Nautilus could save me some effort, and I&#39;m planning to test Pharo 1.4 or 2.0 in some future in which AFAIK OmniBrowser will not be supported anymore.<br>
<br>- Some time ago I&#39;ve modified the OmniBrowser framework to browse 
anything I wanted in the &quot;code pane&quot; (the lower pane typically used for 
displaying/editing code), as we had a complex OODB it was very useful, 
see <a href="http://www.youtube.com/watch?v=VxUaOFRHFPk">http://www.youtube.com/watch?v=VxUaOFRHFPk</a> for a demo. However it 
was not easy to understand the OB internals and make the modifications. 
Have you tried to implement such feature in Nautilus?<br>- There is documentation for developing browsers with Nautilus? Something which explains the basic architecture, how it differs from OB? for example:<br>--Do you have to define a metagraph?<br>
--May I have multiple definition panels?<br>-Do you have a mapping for each node type (class?) with each column?<br>-OB is not cross-UI (it depends on Morphic). Can I use a Nautilus browser within a web browser?<br>- Another thing which is really easy is to define Commands in OB, (although the #isActive logic could become a mess without some care). How it is different in Nautilus?<br>
<br>I&#39;m sure I would rewrite my browsers with Nautilus, my key question is how much of the OB knowledge I can re-use? <br><br>Cheers,<br><br>Hern��n<br><br>-- <br>Hern��n Morales<br>Institute of Veterinary Genetics.<br>
