On my system, wxpython is installed by selecting the packet 'python-wxtools'.
If you have wxpython installed, after invoking the plugin, it will present you with a dialog box asking whether you want to remove control points inside the ROI or outside (ROI = region of interest, the area of the pano you have set your crop window on). I use this plugin mainly to remove CPs outside the ROI. My typical use case is, in the openGL preview, to set a cropping rectangle from a bit below the horizon to just above the mountain tops and then remove all CPs outside this area - when I optimize afterwards, the fit is good in the areas which are most visible in a pano and errors are forced to boring areas like the floor or easy-to-blend areas like the sky. The 'remove CPs from masks' menu point is kind of similar and can be used for the same effect; it's even better insofar as the mask can take any shape whereas the 'crop CPs' plugin only works with the (rectangular) ROI. But back when I wrote the plugin, I think this menu point wasn't there yet. I wrote this plugin originally to demonstrate two things: - it might be nice to pass other stuff to a plugin than just the Panorama data structure - wxpython calls can be used from a plugin to get additional user input The first point was made but noone ever cared to consider passing additional parameters. The second point, if I remember rightly, turned out problematic since it did not work on all platforms. The plugin is still there, more as a demonstartion of what can be done than as a really productive item.
