This revision to L3DT 2.2 is largely a 'look-and-feel' upgrade to make L3DT easier to use - particularly for new users. The main changes include:
Addition of the next button in the toolbar, so that you don't have to remember the right sequence of menu options.
Progress bars now have 'cancel' buttons, as well as time estimates for most calculations (via multithreading).
There's now a delete water body mouse tool.
The mouse cursor is now mode-dependent (FINALLY!).
If you experience any problems with this release, please tell me so.
