You can have icons, checkboxes, neither or both, as decorations on the tree:
There are forty icons (well, one is the default, so that's 39 actually) for you to play with. The icons themselves are from the "silk icon set" from Mark James.
I replaced the regular book/page icons also with nicer-looking true color icons from the silk icon set.
So, as usual, do let me know your thoughts. Oh, and the set of icons will be fixed (at least for now), so if there are any suggestions for new icons, do let me know before v2.0!
The main feature in this release is the portable mode support. When in the portable mode, Guide will save (and load) preferences to a .ini file (that lives alongside guide.exe). To use the portable mode, either enable it from the preferences dialog:
change portable=0 to portable=1 to enable the portable mode.
There are a few other intutive improvements too -- remembering node state, the first visible line per node, search dialog improvements, better east asian language support etc.
So download, have fun, but remember this is an alpha release! Enjoy!
