How to custom TinyMCE?

I dont have a "tinymcewrapper" folder in assets/components/

That was a bad install.
I would reinstall

I have done a reinstall. The same...

Ok, now the tinyMCE don't appear anymore.

I reinstall TinyMCEWrapperDIY serval times. The same. I can't get code-mirror (inside TinyMCE) to run.

Then I install TinyMCEWrapper. Inside that code-mirror run. But I have all the buttons that I don't want.

Therefore I deinstalled TinyMCEWrapper and activated TinyMCEWrapperDIY. I thought the missing files will stay there. So TinyMCEWrapperDIY
would run with code-mirror.

Now no TinyMCE-Editor will show up anymore. Under SYSTEM -> Editor tinymcewarpper is there

Update: TinyMCE show up - > the standard chunk was not renamed.
But, the file to activate code-mirror ist still missing.

Sorry, Version 3 will clarify all this confusion.

TinymceWrapperDIY (as the description says) will not install anything in the assets folder, it's really a Do It Yourself Extra for advanced users ...

TinymceWrapper is the suite - it has everything.

Install/keep ONLY ONE of these Extras!

To maintain your changes, please use chunkSuffix in the TinymceWrapper Plugin settings
