Hello, the following has already happened to me a few times while in designing mode:
Imagine I’m modifying the text of several variants within a speak block. Without noticing/thinking about it, sometimes I click outside/next to the text fields (but not in the middle of the screen, where the right side bar would dissappear), so the cursor is not in the text field. Next, I tap “backspace” on my keyboard, thinking that my cursor was still IN one of the text fields, to further edit the text. Then, all of a sudden the right bar disappears and I notice that by pressing backspace, I have actually deleted my whole speak block! This is especially annoying when you had a lot of text in the speak block(s / variants) and haven’t saved any previous version (Ctrl-Shift-S)…
I was surprised to see (correct me if I’m wrong) that Voiceflow currently doesn’t have an “undo” feature either. But I can image you probably already have that on your list (as it’s quite a basic feature most users would expect).
My suggestions for this case would be: either 1. deactivate completely that backspace DELETES the currently selected speak block or 2. let there at least be a popup for the user to confirm that he/she really wants to delete the block (or 3.: make it an option in the settings to toggle the confirmation popup)
