Request: better override functionality in locale settings

[Matthew Ruffalo]

Hello-

I've been a long-time KDE user, and I must say that Plasma 5 looks
*great*. Everything looks very polished and I'm looking forward to using
it on a stable Linux distribution.

In all of my usage of KDE, I've always greatly appreciated how
customizable the locale settings are. I live in the United States and
have various options set for American English. However, I have
configured my system to use the far superior formats for time (24-hour),
date (YYYY-MM-DD) and measurements (metric over the imperial units). The
Locale settings in KDE 4 allow me to override these settings very easily.

I've been testing out the live CDs available at
http://files.kde.org/snapshots/ and I'm very concerned about the
"Formats" module of the regional settings. The "Detailed Settings"
overrides are essentially *unusable*, as shown in
http://i.imgur.com/onT3zOr.png . (I took this screenshot from the ISO
image named neon5-201408220837.iso.) When I try to override the time for
a 24-hour format, I am forced to guess about a region of the world that
uses this format instead of simply entering YYYY-MM-DD as before.
Additionally, the list of locales is enormous, with very limited
scrolling capability. I am forced to point my mouse cursor at the bottom
arrow and wait as the list scrolls very slowly. The other detailed
settings overrides behave in the same way. In particular, the
"Measurement Units" option should probably simply show "metric/imperial".

In my opinion, this is a very serious usability regression and would
stop me from using Plasma 5. Are there any plans to change the
behavior/appearance of this settings applet?

I searched the bug tracker for anything related to this and only found
https://bugs.kde.org/show_bug.cgi?id=337563 -- I'm hoping that Martin
Klapetek means to say that the *digitial clock itself* won't have 12/24
hour options and that it should be set in the global locale settings. I
fully appreciate and agree with this; I'm asserting that the locale
settings module is barely usable to override the time or date formats.

Thank you for your time and consideration,
MMR...
