Pop-up clouds – a lot more work is needed, but a beta version can be expected within a few days:
►similar to folders – but with all the useful Bubble Cloud features such as variable size icons, different icon packs for each cloud, and auto-population!
►I am still trying to decide on the name of this feature, and the exact implementation (thought the pop up windows are already functional).  
►As soon as it becomes presentable I will make it available in the Beta forum

How should I call it?
►pop-up clouds?
►pop-up widgets?
►folder clouds?
►cloud shortcuts?
►bubble cloud folders?
