these are definitely real life example we experience every day. It is hard to draw the line between simplicity and customisability.
For this our biggest inspiration is Figma. It's amazing to see non-designers drawing things in Figma without getting too many frustration together with designers doing complex and very precise designs & design systems without feeling limited.
Their interface feels easy to start with but can take you very far if you need customization and scalability.
We are far from what they achieve, but that's where we'd love the end up. :D
