• map settings
• solids positions manual control
• control fluid sources/sinks
• simulation time step factor
• simulation computational accuracy factor
• control external forces
• try to move simulation to background thread
• add webgl renderer
• play/pause button
• display fluid sources/sink on map
• change map size
• add forces by dragging?
• change render size (zoom)
• fix sinks close-to-wall bug

Cleanup:

• refactor statistics
• restore pressure view
• fix simulations unit tests
• refactor App.ts
• think about drop React components in favor of plain functions on PixelImageData renderers (for performance and simplicity)

Web workers tests summary:

• not supported yet without eject in CRA: WIP: Add support for WebWorker with worker-loader facebook/create-react-app#5886
• in standard case data are shared by copy. as we need to handle thousands of particles and update them dozens times per second, the copy mechanism starts to be significant blocker
• there is a "Transferable" way of sharing data in newest Chrome. it allow as that second thread not only update given particles, but even prepare draw buffer to be renderer on main thread later
• generally, it's interesting topic and I should back to it in the future. currently prefer to spend time somewhere else (and not ejecting entire app)

webgl renderer summary:

• after some test I decided that there is too big learning cost to do it right and not enough to gain. currently rendering isn't any real problem, recalculating particles positions is bottleneck

I focusing on main project currently, abandoning this toy project.
