Add option to set highest shown directory (simulated root directory)
There should be a way to only show folders and files within a certain folder (that folder would look like the root folder in TWLMenu++). This could be as simple as hiding the back button when you're in the default folder.
Example
SD CARD
⊢ BOOT.NDS
⊢ _gba
⊢ ROMs
| ⊢ Nintendo DS
| | ⨽ <NDS ROMs>
| ⊢ Game Boy Advance
| | ⨽ <GBA ROMs>
| ⨽ <System Apps>
⨽ Unlaunch.dsi
In this example, let's say the ROMs folder is the folder to use for this. This folder would be the default folder (which can already be done), and the "Back" option wouldn't appear in this folder, but you would still be able to access all the files and subfolders inside this folder, and the "Back" option would still appear in subfolders. Basically, it would look like the "ROMs" folder is the root folder (and anything outside of it would be hidden).
So, when this is enabled, the structure would look like this (within TWLMenu++):
ROMs (Default Folder)
⊢ Nintendo DS
| ⨽ <NDS ROMs>
⊢ Game Boy Advance
| ⨽ <GBA ROMs>
⨽ <System Apps>
This could be disabled by disabling it entirely or by enabling the option to show hidden folders and files. Maybe this could be first enabled by pressing the X button with the back button highlighted in the default folder. There would also be a button combo to ignore this setting and go up one directory anyway (e.g., press B while holding L and R to go to previous folder even when back button is hidden in current folder).
