Be able to configure preferences / settings / flags via UI

[nikku]

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

We get more and more feature requests on extensibility / configurability that boil down to one thing: Users want to configure their app in an intuitive manner, and understand how external configuration (flags, element templates) is sourced.

They can already configure via flags, externally provided element templates and config.json, but that is not intuitive; hard to discover. Same applies to startup flags.

Describe the solution you'd like

A settings page allows users to configure their app. That page links to documentation + important file system locations (i.e. global element template folders).

Describe alternatives you've considered

Stick to our "no configuration" paradigm.

How it looks like in Windows Terminal:

@christian-konrad I like everything about this including "open JSON file". 👍

Moving to ready for discussion. We want to take a very first stab at this, and make editing of custom SSL certificates easier available through the visual UI. Cf. #3467.

Given: #3467 (comment).
I propose that we move this to backlog for now, until we have gathered more input from the customer.

Settings might make sense, but maybe it is not a prerequisite for #3467.

Cf. #3477 (comment) for a progress on the linked PR.

Settings could be used to implement #804
