This is something that bugs me too, 1-2 minutes is far too long, in my
computer it takes like 15 seconds but with a testing MacPorts installation,
I think your numbers can be more real life. The framework gets the list
roughly in this way:
1. performs a mportsearch with the regex ".+".
2. Transforms the returned list to a Cocoa NSDictionary.
3. Creates a MPPort object for each entry in the NSDictionary (i.e. one
4. Iterates over the MPPort objects setting their state to Not Installed
5. performs a registry::installed to get the list of installed ports
6. Transforms the returned list to a Cocoa NSDictionary
7. Creates a MPReceipt
8. Iterates over the MPRecipt objects changing the corresponding MPPort
object state (Installed, Active, Outdated).
As you can see, It is a very complicated process and I haven't worked in
make it faster. If anybody has some recommendation, I'll be glad to hear it.

I haven't thought of that, I think I can add it to my TODO and come with a
solution. If I can get the list, It shouldn't be difficult to add.

I got them from the Pallet project. Maybe I should work in new Icons (but
I'm not that good with using Illustrator nor Photoshop)

Yes, It dies in the Framework. I am planing a solution to this maybe by
looking if there are the necessary files in the directory or by catching
errors in the Framework.

Oh, sorry, I think that is my fault as the filter bar uses cocoa bindings.
Adding it to the TODO.

It should work as the framework can handle the need of root privileges
automatically but currently I am changing some things in the framewok

Yes, that is someting that happened with MPActionTool but I have changed
that. now the processes that perform port operations are in the framework
and terminate after doing their work.

Yes, this is something I'm currently working on.
Thanks a lot for your comments and feedback. I'd like to update the binary
version each week to get feedback more easily in what I'm working. I'd
included your comments in the TODO list in
https://trac.macports.org/wiki/MacPortsGUI. I hope to fix some of the issues
you found for the next binary version.
