If visual editor remove cursors synchronization (formula cursor), it is
a bug.

I prefer to alert you before...

No. But what do you mean by "easy-to-use formula editor" ? "easy-to-use
formula editor" is not a specification for an editor. The specification
describe the set of functions you will implement and you expect that
this set of functions will let say the users: ok, now we have an
"easy-to-use formula editor".
In other words "easy-to-use formula editor" is a marketing expression
behind which you can have anything.

For me the current formula editor is already easy-to-use. However it
will be more easy to use if the command window was able to show the
complementary braket or brace. It would be very useful when you have
complex formulas with several levels of group brakets to write.

I think that is, indeed, the least of the things to do if you want add a
visual mode to the current editor.
However the button to activate the formula cursor already exists, but it
does not work if experimental functions are activated.
In fact I would prefer a checkbox to choose the editor mode, text mode
or visual mode.

For that you need to design your visual editor to allow the possibility
to write formulas without using the mouse. For example it would be nice
to write sqrt{} in the formula and obtain a square root.

Best regards.
