Hi,

Something similar has been posted before ([PATCH] Cosmetics: New icons
for backup.cgi), but unfortunately the discussion was not continued for
very long.

Triggered by:

and

I'd like to know whether there is any interest in developing this any
further. In the meantime, patches were built for 'backup.cgi' which not
only update the icons and their order of precedence for better
readability and usability. In an additional step, the 'delete' icons got
'onclick'-confirmation boxes (by Erik!) to prevent accidental deletions.

Another step could be to add this confirmation to other CGIs. This
additional query could prevent some trouble in the future as it happened
to the original poster of the second link above. He accidentally deleted
an OVPN client. No query... I'm already testing this functionality in
other contexts (e.g., firewall rules, dhcp, hosts) and it works.

And the last question: each current lang file contains up to ~600 unused
translation strings. These are summing up to about 5000 strings which
are not used or duplicates and could be deleted. Current size of all
lang files is 1.2MB - we actually need about 900KB. A current patch can
be found here:

At the beginning of this year I built some patches for these unused
strings and some other corrections
(https://patchwork.ipfire.org/patch/1605/) but sadly got no reaction at
all. Is there any interest, should we re-edit the unused translations?

What do you think? Opinions and comments are welcome...

Best,
Matthias
