Thanks! Looks good o me so far.

By the way, I find the icons a little confusing on the clipboard import. Visually, it's not entirely clear to me which is import and which is export, and I generally have to hover over. Maybe moving the arrow a bit further to the side might make it clearer. I think also the way they point to the right kind of make it feel that the load one is taking things out of the application whilst the save is importing into the application. Perhaps making the load/import button appear to the left of the save/export might be more in-line with other applications, as typically load appears before save. But maybe it's just me.
