[pmwiki-users] Should $EnableNotSavedWarning be enabled by default?

[Petko Yotov]

Currently by default PmWiki doesn't warn when people edit a page, and 
try to move away from the edit form without saving.

We have $EnableNotSavedWarning but it needs to be enabled in config.php 
by the administrator.

I added it to sample-config.php, but I wonder if instead we should 
simply enable it by default.

I believe the setting dramatically improves the user experience and 
saves a lot of frustration, especially with inexperienced editors and 
administrators (who have yet to read the documentation and enable the 
setting).

The setting, enabled, might possibly interfere with some custom edit 
forms, although I am not aware of such a case, or with some of the 
existing recipes that do exactly this.

If we enable it by default, anyone who doesn't need this feature can 
disable it with

   $EnableNotSavedWarning = 0;

Even if there might be existing administrators who may be annoyed to add 
this line when they upgrade, I feel the benefit from having the feature 
enabled outweighs the downside.

Thoughts?
