Disable middle mouse click using area mode

I’m used to having the right area of the trackpad giving me secondary click, and the left giving me primary click (this is basic stuff!)

I enabled area mode in tweaks, but find that I’m hitting the middle click more often than the left and getting all kinds of weird and annoying behaviour, such as closing tabs in PureBrowser when I don’t mean to. I’d like to disable middle click or wire that area to be left click. Is this possible?

In the meantime my workaround is to use fingers mode, although this makes right click annoyingly difficult.

i’ll just reply to say I’m having exactly the same issue with GNOME since getting my laptop, especially since it doesn’t have clearly defined buttons on the track pad. Makes it very hard to use as it’s different from every other UI I’ve worked with.
