Fix curve panel in Glyphs 3

Hello everyone,
I really like the Glyphs 2 two-dimensional array of tick boxes in the “fix curve” pannel, I finally got used to it and use it everyday. However, I don’t yet understand how the new fix curve works (I haven’t found any documentation on the website, I imagine it’s not online yet). But could there be a way to have an old-school 2D panel in Glyphs 3? Maybe as a plug-in? I find it’s much more intuitive. Thanks for your attention!

The new one is just like the one-dimensional in Glyphs 2. The two-dimensional one has many problems that I don’t like to fix at the this point.
