Improve drag and drop response time in OpenStudio
When dragging and dropping model or library elements into an OpenStudio section (e.g. dropping a thermal zone into an air loop), the app takes several seconds to register before it allows further input. It makes the App annoying to use at times. Faster response (<0.25s) would improve usability.
General speed of the GUI (especially on larger projects) is a major impediment to using OS for commercial purposes. When our projects get to a certain size, we are just forced to go back to eQuest or use IES VE.
There are limits to how much the modellers can simplify while still getting meaningful results that the various reviewing agencies will accept (USGBC, cities, etc).
