An ideal work scenario, TB-wise for me is:
I'm attending an event (concert, museum, whatever) after work, and I don't want to carry my backpack (right now is a black Piquadro computer backpack which is very flat but can pack Mac Air, iPad pro, my current external keyboard which is not a TextBlade, tupperware for lunch and sometimes also a drink). Hence, I'd like to be as lightweight as possible: lightning-HDMI adaptor, my phone, TextBlade, optionally some phone stand that can hold it portrait. Also, I always carry a small notebook and a bullet pen. Ideally, I can keep the stand, blade and adaptor in the same bag/recipient and it fits in my pocket, bullet pen would be a plus, as well as 53's Pencil which I have started using with Procreate Pocket for iPhone (it's in beta and it's terrific).
On that day, I'll work mostly by SSH-ing into a remote instance, but working with an external screen for size. I may work more on design/architecture with my pen on paper, I may go to a quiet place with the TB, phone and stand. I could go anywhere.
