What I would one day like to see is support in TheIDE for setup projects. Nothing to fancy, just a tool to manage destinations for files that are included with the binary include mechanism and some default layouts in a new project template.
It would be great if we could do the (little) coding necessary to customize a setup in C++, and not have to use redundant-script and WinAPI as in InstallShield. I never understood why my InstallShield setup is taking more time to "prepare setup" than it takes to actually install the data (I have relatively small packages to deploy).
Well, IMO, the way how U++ install (in Win32) works now and how it is created (using U++ code to compile and zip everything) is quite OK.
I never understood what that InstallShield is good for....
