Please provide the ability to apply tags (or labels) to any entry in Proton Pass. The construct of vaults is useful for separately general categories (e.g.: personal, work) but within a large category there are many sub categories where vaults are not the solution. Consider: You have a family and you manage accounts for your children. You can create a FAMILY vault and then tag each entry with each of your children's names. You could create separate vaults for each but then you are hopping back and forth between vaults too often. With the ability to tag entries you can quickly filter while staying in the same vault.

Another example: Say you have pets and you have a number of websites related to your pets. Pet stores, vets, pharmacies, et al. A separate pet vault will work but what if you have a cat, dog, bird, reptile (you really like pets :-) ). Within that vault you are still sifting through a wealth of entries to fiind the one you need when you are only looking for something for your dog.

Currently, the only way to achieve this is to add a tag to the note section of an entry. This works but it is cumbersome and not "clean". With tags you could select multiple entries at one time and drag them all to the tag to apply them. With notes you have to edit each entry separately.
