1. There is something little. The option to copy and paste hotspots between different frames.
There is the option to "duplicate" the hotspots..sadly though not between frames..But like Lyberodoggy said..the Runtimes Frames Merging gives you the option to share the same hotspot with all the frames..so its like copy and pasting it..
The installation windows could be changeable with animations, pictures and or music playing while the installing process.
I think I know what you mean here..that would be cool..Similar to what they have for online games...but they take such little time to install the games for AM..or at least thats what I have noticed..I'm assuming you don't mean downloading process but installation process..~
Form and size of the entrance menue paintable, animations and sounds everywhere
This you can do with Full Version of AM...you can make custom Start menus..for example..I had animations and music on mine..also gifs..as well as video~
Other movements than water waves (filters: something circling, horizontal and diagonal, changing of color intensity)
This you can do, I'm pretty sure..with flash or video files...There are certain plugins that have some really neat features as well..
I think you may have posted this in the wrong thread..here is one that I beleive you can post suggestions..
