Unactive lines in Takeoff reference/little ND symbols

[DenchikGushchin]

Good evening, mSparks43. Thank you so much for your project. But i want to mark two problems in my issue.
Firstly, it's takeoff reference page. There are many unactive keys

Secodly,i think you should make changes in ND. The symbols there are too small.

The 'Key not active' means the function has not been coded yet. I would not necessarily call this an issue.
As for the ND fonts, they have already been addressed in #70.
