I am not big in gdb interfaces, just a user. And I do not see in this window a 
lot of variables mentioned in the code. Actually, only local variables are 
displayed automatically and this is correct and good!
But there are much more...:-))

Yes, there are many possible complicated cases where just "print" will not 
work, I understand. And I do not suggest to use "print" INSTEAD of "watch" 
or "evaluate". Just together. And it seems to be not very difficult to 
implement, no?

I should like to say that you (and kdevelop team?) are a bit closed on the 
concept of the strict, only KDE development. But kdevelop is a great tool to 
be used in many other cases of SW development. I, for example, use it to 
develop embedded data acquisition system with PowerPC processor under Linux. 
Application utilizes Real Time OS and is written in C++ and is debugged by 
using gdb remote protocol. And I recommend kdevelop to many of other embedded 
developers, as it is fast, simple, comfortable, etc. in the field of code 
writing and processing. But debugger interface, if compared to the rest of 
the IDE is less rich (no suitable registers view, no mixed (source/asm) view, 
problems with console and MI interface to gdb, etc.). I am not blaming 
anybody in any way, just telling my own feelings...
