Sometimes I stumble upon interesting commands, settings or procedures that might be useful in the future as well, so I'll document them here and who knows, maybe someone else will find something interesting here as well.
Once Chrome noticed your site using HTTPS it will keep redirecting you to HTTPS even if the webserver doesn't even host HTTPS sites. You can clear the cache and cookies, try to delete the HSTS policy, but nothing works, except this:

Here's a short batch script that allows you to convert a video to a GIF with FFmpeg.
SET filters="fps=%4,scale=%3:-1:flags=lanczos" ffmpeg -v warning -i %1 -vf "%filters%,palettegen" -y palette.png ffmpeg -v warning -i %1 -i palette.png -lavfi "%filters% [x]; [x][1:v] paletteuse" -y %2 DEL palette.png
Usage: togif.bat <input.mp4> <output.gif> <width> <fps>
VariBright is responsible for automatically adjusting the brightness of your display depending on the content shown on the screen. While an interesting idea, it generally doesn't work as expected and leads to a very annoying brightness pumping.

For some firewall rules you're required to provide the public IP address. With a dynamic IP you would have to update the firewall rule every time the IP changes, which can be rather annoying and with many rules also time consuming.
Instead it's best to just add a new address list which then can be referenced and if the IP changes there's only one place you need to update.
/ip firewall address-list add address <IP>
The command line will then prompt you for a name, pick something descriptive like for example PUBLIC.
/ip firewall nat add chain=srcnat src-address=192.168.1.0/24 dst-address=192.168.1.10 protocol=tcp out-interface=bridge1 action=masquerade add chain=dstnat dst-address-list=PUBLIC protocol=tcp dst-port=80880 action=dst-nat to-address=192.168.1.10
EdgeOS is basically a modified Debian system and supports a lot of the commonly known commands.
The most important command or rather key is the ?. It will list all available commands in the given situation.
With configure you switch into configuration mode where you can change the router settings. Leave this mode with exit.
Use commit to apply changes and save to write them to disk.
