Re #1: I will dash your hopes. :-)
I’ve been thinking about writing a plugin to manage indentation, because so far
nothing I’ve seen does it right.
I prefer tabs for indentation. Why? because I don’t want it to be possible to
have the cursor anywhere but a valid indent level prior to the actual code on
the line. I want to be able to set the tab width to what I like and have
everyone else’s code adapt, without modifying the file content. When spaces
are used to indent, that doesn’t work.
Tabs must only be the first characters on the line. After the first non-tab
there can never be another tab on the line. This rule ensures that it is
possible to change the tab width to any positive integer and not screw up any
intentional alignment.
I want to use spaces after the tabs for alignment purposes, e.g lining up
parameters so they appear after the ‘(‘ if a method call needs to split lines.
method(a ,b
c ,d);
<tab to here, spaces to align ‘c’ with ‘a'
int one = 1;
int three = 3;
int five = 5
<always spaces to align after indent level
I want code formatting to respect intentional extra spaces for alignment.
I could tolerate spaces if they weren’t so painful for navigation. I want
everything treated as a tab up to the indent level (based on the program
structure).
Maybe an advanced plugin could keep track of indent level separately so the
editor behaved as if tabs were used to indent, but was smart about what was
detected as the indent width in the file when it was loaded. IT could treat
indenting as if it were done with tabs. When saving it would know that the
file used spaces and it knows how many spaces were used to indent one level so
keeps that number of spaces when the file is saved, regardless of what my
preferred tab width is for viewing/editing.
If spaces are found before tabs on the same line, the plugin could use version
control to find who last committed the file, track them down on social media,
and send a firing squad to their house ;-)

P.S. A NetBeans option to make whitespace visible so we can see when
spaces/tabs are not used consistently would be nice.
