I was looking for stuff more closely tied to the language itself, as opposed to tools related to it. That said, the tools and ecosystem are very important, and I think there ought to be increased awareness of the tools out there (on a related note: people's aversion to style insensitivity seems to partially arise from a lack of awareness of nimgrep).
Unfortunately, I'm not really the most qualified person to be talking about Nim IDEs or the most popular/powerful/whatever Nim tools. I use a bunch of stuff that I've modified to my liking (my fork of [NimKate](https://github.com/ryukoposting/NimKate) and modified version of Sam from [plan9port](https://gitlab.com/ryukoposting/plan9port)). I will be using Kate for the videos, since the lack of syntax highlighting in Sam might be a turn-off to some viewers. I've been mulling over the possibility of doing a video on concepts, probably starting with the AtMost concept I use in one of my nimble packages, then working upward to more sophisticated examples. I'll also do a video illustrating how macros can be used to create useful new syntaxes, and will probably use my ladder logic package as an example with that. If anyone has cool examples of macros and concepts in action, please send them to me!
