One very important thing first: BlitzBasic and all components that are used are brought to us by Blitz Research and Mark Sibly.
This change is done in best sense only to make BlitzBasic Programming for some of us and for certain Projects that are developed under some independent ideas even easier and because in my view the original Editor is the still the best.
I tried several other Editors - some that were even highlighting own Functions - but they were much too slow or the Screen was blinking or they couldn't get patched for these needs or what ever.

Getting started: 

Unzip all Files (Use Subfolder names must be checked) into your Blitz-Directory.

Check if you have Blitz3D-Version 1.80. If that's true you can use this patch at your own risk (as I do and as we all do)
Run the files MakeAndPatchBlitz3DEdit.bb and bin\MakeAndPatchIDP.bb. Make an Executable from bin\PreCompile.bb.

This are all preparations that have to be done. Have fun.
And read on the Website www.BlitzEditorProject.ch.vu more about it. How you can make your ideas improve that project. How to use the new Commands. How to make your own Functions compatible with it. And how to send your Functions or improved Functions to us to share them with others.

In case that gets a good frequented site maybe we start a forum or a chatroom.

To make it clear once again - you can check the Source-code of all files - these files cannot do any harm to your computer - they are free of viruses and produced no errors here, etc. If in case of strange Installations or if your system doesn't like me personally  and it bites the dust - just don't take the risk to use this at all. I am not responsible for anything - Okay - that was the EULA-cheese for that.
