Describe your idea
Have FM prepopulate some custom variables that we can use on our menus. For example:
$FORGE
$MCVERSION
$MCPVERSION
$NUM_MODS

and maybe go so far as to allow us to add our own custom variables

Having such a feature would allow us to control the block of text that normally appears under branding that we all tend to turn off. By placing its elements wherever we desire.

Hooked this issue to remind myself of adding support for these variables to the layout editor.

The variables itself are already a thing, but you cannot use them in the editor.

Variables:

• %guiwidth% to get the current menu width
• %guiheight% to get the current menu height
• %playername% to get the client player name (broken in versions <1.7.0)
• %playeruuid% to get the client player uuid (broken in versions <1.7.0)
• %loadedmods% to get the number of active mods
• %totalmods% to get the total number of mods
• %version:<modid>% to get the version of a mod (also works for forge by using forge as modid; Example: %version:forge%)

Added in FancyMenu v2.0.0! Thank you for your suggestion!
