I have 2 Questions:

1. Is it possible to overlay two Flex Grids like 2 Layer or 2 Levels over each other?

2. Is it possible to overlay two or more Images in the same Cell of the Flex Grid?

In flexible layout, it is not possible to overlay objects.
Because layers objects require absolute positioning and this break the flexible behavior.

When add some hotspots and then change their size or position WebBuilder stops working and must be restarted.
This needs to be fixed.

Is it possible to use normal images for hotspots? Or circle/rectangle with any border or rollover effect on hover...

I am not aware of any issues with hotspots.
What are the exact steps to reproduce this behavior?

Only icons can be used as hotspots.

Ok, only icons. May we use our own icons and if yes, then how?

Also, crispy68 has created many additional iconfont add-ons:
