Simone 'saimo' Bevilacqua has just updated ALS for AMOS Layers System, as it turns the screens of AMOS Professional into layers that can be laid over one another, with complete control of order, colors and opaqueness, while keeping them renderable as usual.
It is easy, requires little knowledge of the Amiga graphics hardware, does not need installation, does not depend on third-party extensions and comes as a collection of variables, arrays and procedures written in fully commented AMOS code - it can be thought of as an AMOS source-level library.
