Would it be problematic in balance, mechanics, or game sense to get a toggle for Mysterious? The spell thief passive.

[Neus]

It's not trivial to change the type of skill it is, which would be what has to happen for this to occur. The alternative would be to add a new skill and/or remove the old one, that is a toggle and behaves this way. Might I ask in what scenarios would you want to toggle it?

[Lolzytripd]

because the user of mysterious cannot double click themselves to see their current stats, and duration of status effects.

[Sawrock]

You might want to hide that you're a spellthief.

[Snake]

because the user of mysterious cannot double click themselves to see their current stats, and duration of status effects.

Mostly this ^

I imagine it could be edited in without removing the existing skill, the stat points/duration on status effects I mean.

[Raigen.Convict]

Can't you use the box with your face in it to tell your hp and fp for you and allies and use the small boxes for status effects for those?

[Exxy]

You mean the Combat HUD? It's been known to be unreliable (although I haven't personally had an issue with it misrepresenting status effects except maybe twice which was forever ago).

[Raigen.Convict]

I've never had the combat HUD lie to me, not once.
