Feature Request: Pressing space bar for equipped magic spell switcher menu

[Abendlied]

Feature Description
Original game feature:
If the player has multiple spells equipped on quick buttons (3, 4, 5, ..., 0) and has drawn a magic spell as weapon the last time, magic spell switcher becomes available. Long and uninterrupted pressing of the space bar opens this equipped magic spell switcher menu. It shows the position of the spell and allows to switch using left (A) and right (D) control buttons.
In that menu, small icons indicate the spell, also showing if rune, scroll or other item like golem heart is used. After a while, an effect preview of the spell is shown as well. The name of the spell is shown on top, the quick button number is indicated on the spell symbol and - in the case of a scroll, the remaining quantity in the inventory is shown.

It appears as if this feature is missing in OpenGothic. Long pressing space in OpenGothic is interpreted as spam-press space, resulting in spam-drawing last used weapon.

Original Gothic 2 crashes a lot on my machine, cannot bring it to a point in game where I have two or more spells, even with insert cheats. I believe G2 has this feature as well though, so I keep it general and not G1 specific.
