Inno Setup looks like a great tool!  I don't know Pascal or Delphi, but I work in software so I thought I'd hit the forums see what I could find...

First, I'm wondering if there is any way when you are creating the installer to customize/add your own functions in Pascal?  In other words does inno setup/delphi give you a finite number of options, or can you get into the weeds a little and add your own code?  If so (and if you're interested of course :) ) here are some links I found that could have some good ideas / examples / useful functions:
 

Pascal Scripting: CreateInputFilePage:

Pascal Scripting: GetOpenFileName

Here's another one that I only had time to look at briefly, but looked pretty interesting and mentioned searching/filtering:

What's the installer written in?  I'd be curious to do some research :)
