Blueprint appears to be the React UI "toolkit" I've been long looking for.

Looking at what this toolkit provides, this looks to provide us with:

• A usable tab / accordion (via the Collapse component)
• A context menu component that could replace our use of ol3-contextmenu
• A menu and portal component that could replace our current hacky use of react-flyout
• A navbar and ButtonGroup component that could replace our current toolbar
• A dialog component that can replace our handcrafed one
• A tree component that could replace our handcrafted one in the legend

And the key thing that binds them all together is a unified look and feel, which is hard to do for an application that is a mish mash of different react components.

The fact that this toolkit is written in TypeScript is an added bonus.

Ideally using blueprints should help us replace the following:

• Using react-flyout for flyout menus
• ol3-contextmenu for the context menu
• Our custom modal dialogs
• Our custom fontello icon set
• Style our various UIs to be more pretty
  • Measure
  • Quick Plot
  • Selection Panel
  • Error displays
