Uninstall: Add support for custom wizard pages like Setup
Handle the UnInstall process just like the Install/Setup process using Wizardpages, and the accompanying event functions.
This would allow for a more complete handling of uninstalls, especially when removing 3rd party sub-installs.

Got my vote. I have several files which are installed in the {userdocs} and aren't un-installed when un-installing the app. Would be nice to see if the user could select them if he/she wants to un-install them also. (conditionally)

After some newsgroup prodding, adding extra dialogs in the form of Notebooks and NotebookPages isn't that difficult, and totally within the bounds of the classes provided to us.
However some extra features could be done for customized Uninstallation dialog support, such as adding a directive or some dynamic functionality to disable the uninstall confirmation dialog (since it would be handled in the manually created "pages"). That is the only big thing I can think of. -

Yes of course one could use a simple MsgBox, but having the full range of making a custom page like the installer would be much nicer for the uninstaller.

You don't need the wizard pages to ask the user things.
You can use a message box in CurUninstallStepChanged(usUninstall)
(Of course, it integrated into a setup page looks nicer :) -

This would be great. I haven't found a way to ask if certain files should be deleted on uninstall yet. That way, there could be a checkbox so the user could decide to keep settings or delete them, for example.

I agree, it would be easier to create more flexible uninstalls.
I think there are also few other issues in uninstaller that makes it less powerful than installer. For example, recently I found that Check in UninstallRun is performed during installation rather than during uninstallation. That was rather unexpectable and also allows less flexibility for uninstaller. -

Assuming you mean adding custom wizard pages. The event functions are already like Setup.
