Dolphin should own built in functions like format utilities (for formatting new partitions and disks) without any needs to download new programs
and also it should have a tab in properties sections to change file attributes
like making it hidden and so on.

this is actually 2 ideas

the formatting one is a dup (full or partial) of:
brainstorm.php#idea44893_page1
brainstorm.php?mode=idea&i=82730#anchormain
brainstorm.php?mode=idea&i=82916#anchormain

and per theBlackCat brainstorm.php?mode=idea&i=38981&page=2&c=172817#anchormain "The bugs.kde.org report https://bugs.kde.org/show_bug.cgi?id=209784. was marked as wontfix

You can already change file attributes. Right-click on the file and click "properties". Things like being hidden are controlled by the file name on linux systems (add a . before the file name).
