           Summary: In dolphin please allow users to increase the maximum
                    zoom (larger size of icons)
           Product: dolphin
           Version: unspecified

         Component: view-engine: general

SUMMARY
I'd like to configure a media center within dolphin. In particular I'd like to
set up a movies folder which shows movie covers as folder icons, has large
folder labels and is zoomed in so that the covers are large.

The best way for this would be to have directory-specific view settings and
have a preconfigured folder view settings profile called "Movies" which
automatically configures all those things dependent on some user variables such
as display size. But these would be separate issues.

It's already possible to do most of these things in an improvised way by
manually selecting folder-icons, disabling preview, selecting the icons mode,
zooming in to the maximum and changing the font size for the icon mode under
Configure Dolphin->View Modes->Icons->Label font->Custom->Size.

This is why the only remaining problem with this improvised solution is the
maximum zoom level: the folder-icons (movie covers) aren't large enough at the
maximum icon size.

This could be fixed in two ways:
- increasing the maximum zoom level and/or
- giving users the option to configure the maximum zoom level (or multiple
options like a maximum zoom level for each view mode)

Currently the maximum zoom is 256px which was probably chosen due to icons not
being larger than 256 pixels. But even icons of less than 256 px should display
properly at a larger resolution. To prevent e.g. less tech-savvy users to
configure the view-mode to look very bad it could be made an option or options.

STEPS TO REPRODUCE
1. Enter a folder which contains a folder that contains an image
2. Selecting the folder's image to be the folder's icon
3. Disable preview
4. Selecting the icons mode
5. Zoom in to the maximum

OBSERVED RESULT
Maximum zoom too small (subjective and depends on hardware)

EXPECTED RESULT
Maximum zoom should be larger or configurable

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.14.5
KDE Plasma Version: 5.14
KDE Frameworks Version: 5.54.0
Qt Version: 5.11.3

ADDITIONAL INFORMATION
I previously asked about this here:
https://unix.stackexchange.com/questions/581870/how-to-configure-per-directory-view-settings-in-kde-dolphin-for-a-media-center
and I will link to here from there.

I might be relevant that the "Zren" fork of dolphin has this:
> Added a few "View Modes" which will toggle "Preview"
> automatically, and "Zoom" to specific sizes which are
> familiar to Windows users.
> Huge Icons, Large Icons, and Tiled view mode presets.
