Feat: Tile mode config improvements

[RockasMockas]

Added 3 features in the config to make using tile mode more customizable/flexible for various setups. This includes:

• Adjusting area sizes/number of areas by exposing the two hardcoded underlying values as config values
• Scaling the font size inside of a tile area, defaulting to base 0.5 and adjusting as needed
• Skipping bisection entirely for those who just want to use tile mode alone without having to press space/enter after

These were pretty high-value updates on my end for my flow, and should be helpful to someone else out there.
