What are the criteria for an ideal CMS?

Question

CMS

I am developing my own CMS, I want to know the opinion of experts.
For myself, I derived the following criteria:
For developers:
1. Component architecture. The ability to simply connect the component anywhere. Separation of logic and presentation.
2. Flexible setting of properties of any element or section.
3. Modular kernel, it is possible to make changes to the kernel without affecting the kernel code itself.
4. The maximum possible reduction in the connectivity of system modules.
For administrators:
1. "Editing mode" The ability to edit any material without going into the administrative part. Inline editing.
2. The most simple admin panel, such that a person who does not understand programming at all can easily understand how to make the necessary settings.
I want to create the best possible solution. Write what you like in modern CMS, what you don't like.

4. The maximum possible reduction in the connectivity of system modules.

Far from a fact. It's not a framework, so it's better to work simpler and faster than it will have a bunch of abstractions like in a "how to do it academically" framework.

For administrators:
1. "Editing mode" Ability to edit any material without going into the administrative part. Inline editing.
2. The most simple admin panel, such that a person who does not understand programming at all can easily understand how to make the necessary settings.
If the administrator is a teapot, then yes, but a normal administrator is not afraid of HTML. It all depends on the intended audience.

Answer 2

It would be possible not to do some kind of "super-universal" thing, but to make various highly specialized versions of the engine. For example, a business card site has its own cut-down version of the engine, an Internet store has its own version, a portal has its own, etc.

Answer 3

modx is very good. Meets all your requirements.
