I've found using system.debug to be a little cumbersome so I created this little bit of code today to help myself and hope that it will help others too.   The most challenging part about this was simply reading through the documenation to find how to create a generic sobject handler and then iterate through the fields without knowing the object type beforehand. 

First thing to do is create a new object called debug.  Add fields for text and timestamp.  Add the controller and vforce page listed below.  From there you can call DebugPlus.writeLog() from your code or ExecuteAnonymous.  You can write a string or a list<sObject>.

Cheers,

Tyler
