A word of caution to users and fix request from developers – Soulver Review

Soulver is a great application, but I found one major issue - tapping on the Delete for a second, will bring up a popup to clear the whole line, or Clear All. If pushed by mistake, there is no way to undo!!! That's a serious flaw! Since it happened to me already a couple of times, and made me lose all calculations, that I had no backup to. This is especially frustrating, especially after constructing very long formulas. Everything is gone in a blink of an eye! Suggestions to fix this: Either adding support to the native shake device to undo, or add a popup window, asking the user, to confirm, they intended to completely clear all calculations! This issue been existing for the past few versions. Was hoping this would be discovered and fixed, but since it hasn't, I decided to let users and developers know of it. And that's the reason I gave it 3 stars only, at this point. Please fix.
