Well, not quite. There's no way to filter by category, no way to see what kind of item a thing is.

A good start would be to simply copy the way 1Password does it, and go from there.

This is great but you need to give them their own categories, not just bundle them in Others.

What is the difference from before?

Tried adding driver's licence but dates are backwards/american stylee.

With Mobile Phone add IMEI as field.

absolutely need this, similar to 1Password, and also the options for custom fields and sections should be under a general drop down of "add more", like 1Password. these are must haves for fully switching over

Fields, structions, classes, hierarchies, object models... and soon you've reinvented C++ (or other/new PL or database implementation), just add typing (as in "types", rather than keyboarding) and behavior (as in "methods") to the thought. Think structure/mechanics/facilities rather than specific data kind groupings and things may become clearer. Whether PP needs some kind of structured data typing facility is TBD. Certainly just blobs of data in a note is paltry, though, IMO.

Please at categories or tags so we can classify passwords within a vault

Alternatively, instead of Proton providing all those types, one could allow users to create and save their own item types / templates.

Creating a single item from scratch is now possible; saving it (and thus re-using it) unfortunately not (!).

I have posted this idea here:

https://protonmail.uservoice.com/forums/953584-proton-pass/suggestions/50197935-save-custom-item-types-as-templates

The latest update of Proton Pass added 14 new item types, plus fully customisable item creation from scratch.

The status of this idea should probably be advanced to "STARTED" or "COMPLETED", as appropriate.

The identity section is super helpful, but it feels a bit too rigid right now. Not everyone stores the same kind of info—some might need to save things like “Library ID,” “Health Insurance Number,” or other personal details that don’t fit into the default fields.
It would be awesome if we could add or rename fields ourselves. Customizable fields would make the app way more flexible and useful for different people and use cases.

Bank cards + type of payment system (including international and local ones) + expiry date + CVV/CVC

Regarding Tax ID - it is very dangerous thing, as every country has it's own format for Tax ID, so Tax ID itself without country's name is nothing. Or one will need to implement arbitrary text field for it (as tax id could be number or numbers + letters). The same for passport numbers.

Item types and templates are the biggest issues for me, trying to migrate from Datavault. There surely are some very common ones, like bank account, software activation keys, local user accounts and logins to encrypted volumes...
Notes are a workaround for some of that data, but it would be nicer with dedicated fields in a vault record. Very often there always is a basic "login name" and "password" situation and some extra fields that vary. Maybe the most elegant solution is to let users create their own custom vault record types.

Currently, Proton Pass (PP) allows text notes to be associated with vault entries via entry edit. However, while the feature gives the appearance that notes have two parts: a field name and the actual text note. The hint text in the edit box shows "Field name", but then there is no facility to enter separate text that is associated with such a field name, for the "field name" becomes/is the actual note!

It would be GREAT if one could indeed have a separate field name for vault notes, e.g., "Activation code" associated with the text "ASDFJK-QWERTY-POIUYT-ZXCVBN" (for a software program, e.g.). Also, being able to click-to-copy the associated text (ONLY! Not the field name) is the obvious desireable capability desired.

Also SSH Keys would make sense. 1Password has this and it works great.

And add an SSH Agent / CLI around the Keys

One could create their own vault, but in particular the option to create and share Wifi-QR codes would be a helpful new feature!

This would be HUGE especially with some older video games/programs need a serial key or subscription authorization.

Allow users to store Wi-Fi passwords in the app.
