Ipad?..huh, that´s huge, I used an armwrist clock watch tv
Another tip, there is a free plugin called gene, which will grow branches from selected (quad or tri) polygons, but without no manual control handle like magic bevel, and it may also cause the branches grown to intersect with eachother.
It´s a very old plugin so it will probably not work in Lightwave 2019, haven´t tested though.
And you can also use PX_bezier in extend mode, you could select more polygons but they would all follow the same curve handles yielding often not wanted results, unless you want that and perhaps twist them..wich can give a braid look with two extended polys from a mesh.
So pz bezier after selecting a poly..and extend, use straight divisions, and smooth handles, you can add or remove handles and move handles as you please while the tool is active, taper the end.
It´s similar to magic bevel in the sense that you can edit the spline curve and the divisions..and easier to do so and with more control than in magic bevel, but it can not draw it continously, just add handle along the pathway to extend.
Also forgot, if you use px bezier, hard to find perhaps..not available directly on the lightwave plugin site cause links are broken.
Anyway, if you make a nice branch path with px bezier in extend mode, you can save that path out within the px bezier tools setup tab. close the newly created branch made, select another polygon and reload that path. Now that will yield a not so wanted direction extension (same as the previous) ..so go to the tube tab and click on the polynormal direction.
That way you can have the same type of path curve extending out branches, but in the direction of the selected polys normal.
