[Checkbox: Can have Children]

Hey around there....can someone explain the function of "can have children" checkbox in the fixture tab of the builder? How should I understand "Describes if it is possible to mount other devices to this device"...does it mean in the end I could use under a same fixture ID (in the lighting console) other fixtures? Does it mean to work with subfixtures? I don't really get this option.

[Linear Beam Output For Linear Lens Fixtures]

when will the next update be? I guess many fixtures depends on that! For example if you try to create a strobe (like the Martin Atomic, Clay Paky Stormy or GLP JDC)...its impossible to create a fixture this way!

[Builder Problem]

I am a really pissed!

I tried to create the Martin Atomic 3000 LED and just finished all and then the builder showed after clicking on Macros (which should have been my last step). The screen got blank and nothing worked anymore. That means 3 hours research, typing and creating was done for nothing! Why the hell this builder has no chance to store steps and start maybe even creating at a later time? It is absolute not convinient to create a complex this way.....for me it mean, I lost my mood to create a fixture again.?
