Exactly! However, NuttX can replace ESP-IDF if desired. Espressif 
itself approves and provides an HAL for this access. (Same goes 
for Zephyr)

Re: Fluid 0.6.0 — UI library for D

Fluid is a library I started developing 3 years ago when I 
joined the D community, after failing to find a suitable 
library for my gamedev project. Developing user interfaces 
through websites, games or applications is something I've spent 
a significant amount of time in the past, so I saw this as an 
opportunity for developing a solution that combines the best 
aspects of different frameworks I have previously used, whereas 
targeted at web browsers, mobile applications, games or 
desktop. Similarly to how many praise D for being both great 
for prototyping and amazingly scalable, I found that I would 
love to build something that shares both of those traits.

Wow. Congrats on your project, it looks interesting and visually 
modern.
