<p>I recently upgraded to Delphi 2009 and was disappointed to find out that I couldn't easily replace one VCL component with another. The best answer back was that <a href="http://www.gexperts.org" rel="nofollow noreferrer">GExperts</a> could be used to do this. </p>

<p>Is it worthwhile to petition Embarcadero to incorporate some or all of the capabilities of GExperts right into Delphi? Which of their "Experts" do you use most and would like to see in Delphi?</p>

<p>Or is GExperts best left as a community Open Source addon?</p>

My number one GExpert is Grep Search.
Close second is the Procedure List window.
Also very handy are the various keyboard shortcuts,
and the toolbar embedded in the editor - I have a few
buttons on there; like CPU-view, Project Manager and
the selection-tools as a dropdown (like sort selection).
Sometimes I use the Clipboard History window.
And even more rarely the ASCII windows.
Everything else I don't touch really.
I know the procedure-list could also be found in the structure-pane of Delphi 2009, but somehow the fact that I can press Ctrl+G to get a window with quick filtering and preview capabilities is more productive for me.
Same thing for grep - the GExperts' version is way more powerfull than the standard Delphi search function.
If these two (and maybe the clipboard history) where embedded in standard Delphi, I probably wouldn't install GExperts anymore.
But on the other hand : I do like the fact that these solutions are available as open source - this allowed me for example to add section-filtering to the grep-search, which otherwise wouldn't have been possible for me...
