Hello everyone! In the last two weeks we released updates on VTT that include copy and past options in the context menu. In addition to this, you can now multi select doors and windows, regardless of the layer, by holding down "Shift" while dragging, allowing you to Copy & Paste multiple doors & windows at the same time. This modifier keys are included in VTT Settings > KeyBoard Shortcuts > "While using the Select Tool" section. We'll be closing this thread and releasing back your votes so you can use them elsewhere!
