There are effectively two versions of the text: the slightly higher
level, or 'marked up' version containing these special controls, and the
'rendered' version you see displayed on the screen.
You're suggesting doing away with the controls, working only with the
rendered snapshot version. Which means instead of pressing Backspace
once to delete a tab, you might need to press it 8 times, or 1 to 8
times if not at the start.
This is little different to inserting hard newlines at the end of each
visible line of a paragraph, to ensure that it is shown how you want it
and isn't 'reflowed' depending on the width of someone's display.
Which work great - until you have to edit the text with those newlines
present, which can be a lot of work.
So really you want to keep and work with the original version, not the
In the case of tabs, it might be possible to take the rendered text (I
call it 'flat' text because the tabs have been flattened out) and
reconstruct the tabs, but there are some problems (are those 8 spaces
one tab, or two or four, or were they just 8 spaces?).
It might be a little easier if the text represented, say, Python source
But it would be better IMO if tabs were used, with some scheme for
suggesting the tab width (or set of tab stops) that is recommended (eg.
a comment at the top).
