countless units are missing from the uses clause

[ChristianDenk772]

These demos are simply CRAP. In countless demos, various units are missing in the uses clause. Nobody who wants to test the product adds these units manually.
If you're asking that much money for for a product you should keep it up-to-date.

We use this repo to automatically build the demos with all the supported IDEs (from RAD XE to RAD 11.2 now) and we include the binary with each installer.
We published this repo here at github so everybody can get the sources of the distributed examples easily.
So we don't use to open these projects with any IDE. However, I believe the IDE should automatically add missing units.
Could you please detail some of the demos presenting this problem and what IDE are you using so we can give it a try?
Thanks for the feedback.
