I could really use a tag to indicate specifics about technical streams. Currently there is only really an Engineering tag to very broadly cover a range of technical subjects and activities, and adding something like a Science tag for scientific demos, discussions, or applications, and adding something like a Repair or Maintenance tag would cover streams of repair demonstrations or technical troubleshooting which is difficult to represent in tags currently.

There is some room for flexibility in what they ultimately are, but if I want to troubleshoot a broken circuit, for example, I can only call it engineering, which is an extremely broad description that incorporates dozens of fields, hundreds of subjects, and thousands of broad activities. If I want to demonstrate some scientific process or equipment, again the best tag is just Engineering, even though it wouldn't necessarily be about the application of the science and may not be focused on creating a project or design.

These sorts of subjects likely resonate with some of the twitch audience and could be useful to find and differentiate streams trying to show some of these aspects for entertainment, education, or work demonstration purposes.
