I was trying out one of the new features with LTI tool placement, being able to make an LTI System tool.
However, after I created the LTI tool placement as System tool, I don't see it as a choice under the Community > Tabs and Modules > Tool Panel > Add Tool
I can get it to show up if I use the Oscelot Basic LTI (yay Stephen Vickers)
ps. I do see LTI Placement as System Tool in Q2 2017; but there seem to be some known issues with that in Behind the Blackboard (e.g., 000047357 Adding a System Placement for an LTI Tool Produces Check Constraint Error )
