Workflow features:
Low VRAM friendly! Just use the Flux model of your choice.
Layout optimized for 16:9, aka your typical computer monitor.
Organized space for notes while you work.
Notifications at key steps so you can back out while building.
All nodes that you don't need to use regularly are minimized to avoid clutter.
As always, thanks to the community for sharing workflows and techniques! I just rearranged them in a way I think is suitable for heavy use. :)
