A bit of background on what the OP asks for. In AutoCAD, TAN and PER are snap modes. LINE from [here] to [here] to TAN to [this curved entity] to MID of [this] to PER to [this line] and so forth. Importantly, the on-the-fly selected snap takes precedence over existing snap modes. So I might have grid and endpoint snap selected, but if I click "Snap middle" or type MID on the command line it will go to that.

I have the snap modes aliased to their ACAD names so that's how I use them here.

In LibreCAD we can chain some snap modes into a LINE command (like MID or END) but not those; they seem to be separate line commands TANPC, etc. It is a bit of a mental interruption to need to pick the line mode before starting the line, or to have to discontinue one line drawing mode and start another. Also the snap functionality overall takes a little getting used to. AutoCAD has a "Snap radius" which helps you pick the END, MID, CEN or whatever you want or avoid snap altogether by just not being near enough to another feature.

BTW I think the 15 degree thing is not useless. There are plenty of hexagonal and diagonal geometric features that use those angles.
