[request] user variables in bold

[compsystems]

user variables (A, ...Z, M0, ..., M9, L0, ..., L9, Z0, ..., Z9, ), in history panel, to display in bold, with the purpose of identifying them easily, this feature is available on the fx-CP400.

Many users on this forum, some assumptions BUGs, but the problem is that entered user variables as variables of calculation

default user variables have zero value X=0, Y=0, ...

Is good Idea?
