@PassThePeas (and maybe also to @Leo or any of the devs) - I have noticed that since I installed both of your Tabler iconsets (and also your MS Iconset) it took more than twice as much time to open the Icon selector in any/all of my buttons. I have no doubt that this is caused by those new sets, because when I removed the two Tabler sets, everything was back to normal. (The MS iconset is also large, but the two others are each more than twice as large).
What I do not know, and did not investigate, is whether this is related to the size of those sets, or rather the fact that these are SVG sets. Or maybe even another factor (e.g. some irregularity in your xml files).
Any thoughts? Did you not experience this yourself?
