It is either impossible or incredibly difficult to implement.
I thought so too, or probably it would've been implemented ...
The current default is to keep the 99 most recent items. If this is not enough items for you then you should probably use the log file.
the history is so much better then the log that pushed me to make the proposal
I will see about making this number a user adjustable option, but keep in mind that increasing this number too much will use more memory. Since each item stores the last result (if any) it can add up fast, especially when doing web scraping etc.
it will be great. Maybe a temporary override ... this way when VC restarts it goes back to it is reasonable memory footprint and no one complains
in fact it might be a good way to reduce VC memory footprint once everything running smoothly, one can reduce for 10 lines for instance ...
