HTML Help:
Only supports the icons displayed in the Change Icon list. These are an old set of icons dating from Windows 98 that are still hard-wired into the Microsoft HTML Help CHM viewer

ePUB and Kindle Mobi eBooks:
These formats do not support TOC icons at all.

WebHelp and Windows eWriter Help:
These formats allow you to use your own icons. In the Project Explorer go to Configuration > Publishing Options > WebHelp > Navigation to select your own icon graphics. You can select three graphics: two for the open and closed state of chapters and one for topics that are not chapters. In addition to this, the individual icons from the Help+Manual TOC used in these formats are an updated set that are more modern than the Windows 98 icons still used by the Microsoft HTML Help CHM viewer.

Every topic file and every TOC entry stores the date and time it was last edited. These timestamps are normally only changed when the topic or TOC entry is actually edited, they are not changed when the project is saved.

Topic file timestamp:

Click on the topic entry in the TOC or Project Files list. The topic file timestamp is displayed in the status bar below the editor.

TOC entry timestamp:

Hover the mouse pointer over the topic entry in the TOC or Project Files list for a second or so. The timestamp is displayed in a popup tooltip along with other information. (Mouseover hints must be activated in View > Program Options > General.)

Changing timestamp output for WebHelp:

If you wish, you can change the timestamps for your HTML topic files in WebHelp output to the time the files were published instead of the last time they were edited. This setting is in Configuration > Publishing Options > WebHelp > HTML Export Options.
