I think that this would be false security. It is possible to open the vault with SQLCipher outside the Enpass UI and there is no way to implement this self-destruction in such case.
Your password has to be strong enough and it would be good if UI would freeze for a minute after eg. 3 wrong attepts.
desktop Enpass
I select Export to JSON (or TXT)
it will not export trashed (archived ?) items
pls. add export setting to include active/archived/trashed items, where default would be only active
I have the same issue related to my password items. When I change password I will not see the "Password history" text on bottom as on your 2. screenshot.
