[eclipse-clp-users] Debugging and Development

I'm currently using a text editor and the eclipse tracer/inspector for 
debugging .. but i find this very annoying, because i'm missing several 
features that i'm used to have from other development platforms (..like 
Eclipse for Java).

At first, i want to know if there is a special Prolog development editor 
? found one for Eclipse but that does not support EclipseCLP. I only 
want some simple features like auto completation, syntax highlighting, 
call hierarchy, syntax checking ...
What is everyone else using ?

Additional better debug capabilitys would be very handy ... but i assume 
there is no other debugger ? But i hope there is a solution to a debug 
problem i have very often:
When i get a "real" error, not something like predicate not found (a.E 
instantiation fault in call(_8087) ), i want to know where and when .. 
how to ?
