The ability to create new sensors/devices very easily using drag & drop feature is one of my favorite features in this platform since it saves time compared with other platforms that require code writing or programming knowledge! I also like how easy they make creating dashboards as well; you can do so without any coding skills required at all but only by dragging items from their library menu into your dashboard page layout area (similarly when adding widgets).
It's not much yet because there are no issues reported about its performance though i experienced some minor hiccups here nthere while designing pages etc., nothing serious tho just small glitches sometimes during development process where everything works perfectly fine then suddenly something wrong happens again after few minutes later - maybe due too many users accessing same website simultaneously? Not really sure if anyone else has had similar experience before me regarding such issue mentioned above however please feel free share ur thoughts below wtih.
