That snaps does not have dependencies is a nice theory, but as you said
that some snaps use platform snaps and without them they do not work. So
what should this relation be?
The problem I see is that the software center does not provide the information,
which snaps are required to run an installed snap.
In the case of notepad++ I realized the dependency to wine only, because I
analyzed the problem with the snap command. But software center does not give
this information, nor does it solve the dependency.
Also when starting notepad++ no information is given, that something is
missing. It simply does not start.
So the question I have is: How the casual user should recognize what is
missing to run a snap?

Title:
Installed snaps miss dependencies and permissions
Status in gnome-software package in Ubuntu:
Opinion
Bug description:
When testing some text editors I have stumbled over multiple problems,
after the software is installed.
The first test was with notepad++. After installing the snap nothing
worked. The program did not even start, nor provide some information
what is wrong. After checking the interfaces of the notepad++ snap, I
assume that there is a dependency to wine. At least the "notepad-plus-
plus:wine-platform-plug" let me guess it.
I was a little bit surprised that additional software is needed,
because the software description in the software center did not
mention any additional dependencies. Also I am used that the required
dependencies are installed along with the selected software.
I did not want to experiment with wine for now, so I have selected
another editor: notepadqq. After the installation at least the program
can be started, but no text files can be opened. The bug is also
described at the project:
https://github.com/notepadqq/notepadqq/issues/822
On the Open File dialog a file system is visible that is not the file system
of my PC. I guess it is the file system of the confined environment. The
problem is that a text editor that can not access the files of my PC is useless.
I had to install notepadqq with the classic option, so the file system of my
PC can be accessed by notepadqq.
The problem of software center is, that this step is not possible
within the software center, but only via command line.
I think it is important that the software center consider the dependencies
when installing software and give the software all permissions needed to run.
When permission should not be given without review/check/.... the user can be
asked what access right a software should get. At least an information should
be given, that permissions are insufficient and how this can be changed.
