I use Inkscape tabbed box creator to (duh) create tabbed boxes. The saved file imports to LB as a series of coincidental-end-point discontinuous lines, even when grouped in Inkscape. I’ve not yet checked to see if there’s an easy way to join end points within Inkscape. The top-of-head manual method is tedious and LB’s Select Open Shapes and Auto-Join options are fewer clicks and work great.
Today, I noticed that when such object is selected, the marquee (aka crawl) is clockwise on the selected open shapes and when Alt-J is invoked, the crawl reverses direction. I thought I had stumbled across a wonderful feature, but I’ve since discovered after a single test object that it’s not consistent.
Is this a genuine designed-in feature or coincidental?
