Hi, I'd like to be able to open the debugger without the notifier... when programming the notifier does help really (at least to me...). I modified StandarToolSet class>>debugError: anError to pass true as parameter to the full: keyword of #debug:title:full, but I was wondering if there was a preference to do this whitout modifying the code. Also, what does the class OTToolset do? The DevToolSet delegates to it the messages when installed, but the pharo image does not have it install. And the last question!, I'd like the debugger to open in a bigger window. I know I can press the "expand to full screen" button, but I'd like the debugger window to be 3/4 of the screen when opened automatically. I did not find a way to configure that... does it exist? if not, what is the message I should send to the debugger morph to do that? Thanks! Hernan
