Good solution to edit CHM files

I like this program for its ability to edit CHM files. This, I believe, is done in a very professional manner, and it was extremely handy and useful for my CHM File that I developed for my online guitar training software.
I liked the number of tools to edit images, text enrichment, etc.
Seems like this is a powerful tool, and there has been a lot of progress achieved after its initial release.

Easy and helpful for everyone

CHM Editor is responsive to user commands, comes with a help file, supports keyboard shortcuts and consumes a moderate quantity of CPU and system memory. The tool did not cause the operating system to freeze, crash or pop up error dialogs during our testing. However, its features are not oriented toward skilled users only – on the bright side, this aspect makes CHM Editor is a straightforward solution for viewing and editing CHM items.
