This menu allows you to customize the remaining time of a demo and add keyframes with commands in a given minute and second.

The 2020 edition now has the seekdemo command, so it is no longer necessary to use gamespeed, but you can still download the old version for Collect Edition below.

Installation
2020 Edition
Move demoeditor.zip to your sauerbraten root folder and add the following line to your autoexec.cfg file:

addzip demoeditor.zip; exec demoeditor.cfg

To open the 2020 Edition menu you can either type /demoeditor or add an "edit" argument to the demo command (/demo anydemoname edit).

Collect Edition
Move demoeditor_collect_2019.cfg to your sauerbraten root folder and add the following line to your autoexec.cfg file:

exec demoeditor_collect.cfg

Type /demoeditor to open the Collect Edition menu.
