Both sound pretty nice ideas and do not seem available currenlty without coding the skin and widgets

Of course it needs to be coded - or how else does software work?

:) I mean it isn't currently an easy option without the b2evo installer coding a specific skin and widgets, whereas what you want is the coding to be done at development level. Appologies if it wasn't clear what I meant.

This is a feature request as this one is:

I am spoiled by TYPO3 and I am sharing some ideas/experiences gained with other applications.

These FRs enhance usability and user experience and B2E devs can decide it they can use this output as an constructive input.

Enjoy!
