Change/remove or add Key File to existing database

[shuvashish76]

KeePassDX v4.1.0 now supports "Key File" generation but only while creating new database. Request to change/remove or add (if not added before) Key File to existing database.

Is your feature request related to a problem? Please describe.

Ok Settings > Master key > Change master key does show these options

but suppose I want to change or remove only Keyfile or Kardware key then I've to re-type password. Same for passwords (if you want to change password without changing/removing your oldKeyfile or Kardware key)
We can't change one option without affecting other options.

Describe the solution you'd like

Instead off all the 3 options under one "Change master key" make the categories separate under Settings > Master key similar to KeePassXC.

• Master key & related options
• Key File & related options
• Hardware key and related options

Additional suggestions

Perhaps better to rename "Master Key" (Settings > Master key) to "Credentials" as we'll manage Master Key, Keyfile, Hardware key all from this page.
So final would be

• Settings > Database > Credentials
  • Master Key
    • Change master-key
    • Remove master-key
    • [OR] Add master-key
    • Renewal
      • Recommended renewal
      • Force renewal
      • Force renewal next time
  • Key File (under "Additional Protections" sub-heading not as separate page)
    • Change Key-file
    • Remove Key-file
    • [OR] Add Key-file
  • Hardware key (under "Additional Protections" sub-heading not as separate page)
    • Change Hardware-key
    • Remove Hardware-key
    • [OR] Add Hardware-key
