Some ideas

[StefanCohen]

This is a really nifty plugin. Especially for other plugin developers. I know this is in early development but I gave it a try and I really like it. I have some Ideas for improvements.

File destination setting: It would be great if you could set the destination path for the output files in the plugin settings. When running the plugin as a service (i.e OctoPi) the plugin will throw a permission error since it can't write to whatever the default destination folder is.

Module/Function filtering. You can use filter_callback on get_func_stats API to filter on functions, modules or whatever available in YFuncStat object. A setting to enable filtering and a filter string would reduce the noise. A drop-down that enumerates plugins and/or plugin methods would be a big plus.

Display text output in tab: You could add a tab view to the plugin and display the output of yappi.get_func_stats().print_all() there. The tab could even include start/stop buttons to profile OP between prints.

A pretty cool way of displaying the profiling result to the user is to transform the pstats output into a png using gprof2dot -f pstats test.pstats | dot -Tpng -o output.png. I guess that could be a way to analyse the results for those who don't have access other methods.

Very nice ideas @StefanCohen! I had some of those in mind but you took it to the next level. :)
