chronos's Issues

[Request] Search feature

As someone who have more than 50 2fa items, it would be great to have a Search feature on the list.

[iOS 18] App crashes/closes whenever I scroll the list

I'm not sure if this is an issue with iOS 18 or if it happens on 17 as well.

This only happens when the "Tap to review" feature is off.

Steps to reproduce:

• Open app
• Scroll the main view
• App crashes and closes

Also happens when:

• Open app
• Change the sorting to anything
• App crashes and closes

My suspicion is that whenever the list refreshes the application crashes, but unfortunately I cannot debug and confirm this.

For me, this is a blocker to use, but I appreciate all of your work and have high hopes for the future of the app though! :)
