Add Ability to Select Previous Level

[Dariosky-01]

Greetings to all

I wanted to point out that there is very often a need to go and research the level that was opened previously after you have passed to the next level.

When, when you click on the button with the arrow indicating the passage to the next level connected to the first one sought at the opening, often, not always being the initial level set in the second connected level (for returning back) but a third and different one level, it could annoy the fact of not being able to go back with a click with the simplicity with which it was passed from the first to the second connected, as is easily done with the "forward" ("➡️") button to go to the next level set in the open starting level.

So I would like to suggest, given that this problem forces you to often open the "choose level" functionality for April the level list and to reselect the level again, which in any case had previously opened starting ap, I recommend adding a button in the GUI among the large buttons at the top, such as the one to select the next level ("➡️") which appears like this "↩️" placed previously to the "forward" button ("➡️") and which automatically settles with the level chosen outdoors in Foundry or later, at the levels that could be chosen each time the "choose level" function is used by updating the address of the starting level.

This should make life a little easier for everyone.
