[Solved] Triangle (or Polygon) with Rounded Corners?

Hi Guys!
Not a priority item, just wondering...
Draw has Basic Shapes including Rectangles & Squares with rounded corners.
Yesterday, I happened to want to draw a triangle with rounded corners, but did not manage to find any way of doing that, even after quite a bit of searching.
Is there any way of drawing triangles, or other polygons, with adjustable rounded corners?
Thanks!

Rounded corners only available for rectangles, I believe.
Inkscape has an option for "rounded polygons", but with that, the entire sides are rounded (no straight line segment), with sharper curve at "corners" and only a slight bend for the sides. See this tutorial

Here are some that I made; I just scale and tweak these as needed. The rounded corners are just Bezier curves; I adjust them by eye, so it's not a perfect result, but often "good enough".
I made the first one, very tediously, with circles for the corners, but I haven't come up with a simple construction for doing that with differently-sized circles.

PS: Ok, I had an idea of how to make it relatively easy to make precise rounded triangles--not as nice as the rounded rectangles, of course, where you can simply dial in the amount of curvature, but still possible in under a minute
This uses Draw's ability to snap lines to each other's endpoints--once you have positioned some lines exactly, you can use the ends as guide points. With guide points for the corner arcs, you can connect the arcs to form a closed, triangular shape.

Thanks, Acknak, for that idea & for the detailed explanation!
I learned some useful stuff there, including "connect" & "close curve"...
Much appreciated!
