This is a thread where we collect small tips and tricks that can improve the Qubes experience for most users. We want to create a one-stop-post where people can quickly find and implement changes to their systems instead of having to search for and visit a hundred different posts.

Feel free to contribute to the tips section of this wiki post, below the line.

The following guidelines are subject to frequent and major changes while we figure out how this might work

1. If your tip cannot be condensed into a few lines, it doesn't belong

1. If your tip is niche with regard to the Qubes userbase, it doesn't belong*

1. The "Minor" in "Minor Optimizations" means, "doesn't take much to implement", so do post your high-impact tips.

1. If you're unsure whether your tip belongs, ask

1. Give credit (even to yourself) and add a link where applicable

1. Follow the established style convention as much as possible  
2. Feel free to add new categories if necessary  
3. Discussions regarding specific tips belong in their own thread--unless discussing whether it belongs here.

* ^{What's 'niche' is going to spawn a lot of debate and angst, but this constraint is necessary to prevent this post from getting bloated and mostly irrelevant}
