Below is the must-have features request:
-
Relationships between tables. if you can see the screenshot below I am trying to create a relation between two tables but I am not able to drag and attach the relationship arrow.

-
Import/Export diagrams (Currently can export as PNG, SVG, and Export to databases). Can we have later edit functionality? for example, I am writing a database design and will take an approx full day to make a perfect architecture. Before my lunch break, I have 50% completed and I want to continue the design after lunch so there should be an option to export the design that I can continue it's editing by importing it later anytime. Currently, I have to keep my computer running all-time in lunch break OR need to export the design to the database.
Thank you
