Customizable widgets' palette

Hello guys 👋!

We wouldn't be diagramming freaks 🤩 if we didn't mention our huge diagramming affection. Here's the example of the GoJS use in terms of adding several controls 🎛️ in the data inspector, or, as others may call it - the property sidebar. The mentioned functions are customer source 🤝, location 🏡, mailbox 📪, and tags #️⃣. Simplicity and usability - that's our secret!
