Re: Register window workflow / potential advanced features

Hi,

I have some questions and comments on this.

PS: I am very new to this kind of work (I mean GUI developing, workflow 
design), if there are any stupid errors in my comments, please forgive and 
correct me.  :-)

Sorry, what do you mean by vector - formatted registers?

Maybe we can go further to copy the snapshot into a clipboard?

Sorry, can you explain a little about real-time?  Did it means to update 
the values of each registers after each actions?  That is great I believe.

Maybe we can first determine which section this address belongs to, to 
say, code section, stack section, heap section and so on.  If the 
address belongs to code section, we can try to display the function / 
source line; if it belong to stack / heap section, we can try to 
display the variable / data structure it points to.

What about displaying each flags in the status registers (such as EFLAGS, 
MSR - machine status register, FPSCR -floating point status control register
and so on), and also update which flags is changed and which instruction 
does that?  I believe this is very helpful to track problems.
