Can i open big files with the LayoutEditor?
Yes, there are no limitations in file size in the LayoutEditor -- in no version. So even with the basic version you can open 100Mb, 5Gb or even 30Gb files. The only limitation you have is your amount of memory. As a rule of thumb you will need about 4 time more memory than the GDSII file size has. The LayoutEditor make no difference between RAM and virtual memory (except performance of course).
Boxes got lost with photo mask creation. What to do?
The box feature was introduced to the GDSII file format more than 20 years ago. However it is still not supported by some other programs. Activate the option 'box elements are saved as polygons' to avoid this GDSII feature. (SetupDialog -> Fileformat ->GDSII)

What is the design flow?
A fix flow how to do a new IC or any other design may be convenient for an inexperienced user as any step is given and you don't need to think about the way your develop. However it reduces your freedom to design in the best way and may limit to archieve the maximum possible innovation of your product. So the LayoutEditor did not force you to do a fix design flow, but supports you to setup an optimal flow by a large variety of features. Even if an existing feature does not satisfy you, you can easily integrate an external tool.
What design kit exists?
Of course there exists a lot of productive design kit in the world. Interoperable physical design kits (iPDK) become more and more popular and are already suppliered by many founderies. These iPDK can be used with the LayoutEditor. Included in every LayoutEditor package is the OpenCellLibrary. That is an educational PDK and not intended for productive use. It can be used as a template for creating own PDKs.
