It's too dangerous to climb on a ladder to repaint the ceilings (and I'm old), so I 'paint' the PB help file.
Screenshot Actual/New
Just replaced the colors and fonts to modernize a little. (Yellow background to white, Courier to Consola etc)
No modification of the original text contrent (PB v5.72 LTS)
The page of my site is in french, but I also repainted the English version. Direct link to the English instruction and file.
To use it in IDE: Close PB IDE if open, rename or save your original Purebasic.chm (or move-it) then replace it with Purebasic_572_En.chm and rename it in Purebasic.chm. Nothing will be changed in registry or anywhere else.

(This is a Windows security 'feature' with .CHM file)
There is only one file that you just have to put in place of the current one (after renaming it)
There are no changes in the configuration or in the registry. So you can go back at any time.
Enjoy
