### 4/5 — Extremely useful, but...

*2018-04-18, version 1.0.2*

Please add landscape viewing mode such that the app can be used on iPad Pro models without having to rotate screen each time (insanely annoying)... thanks

### 3/5 — Force per length needed

*2018-03-24, version 1.0.1*

This is basically a pretty generic unit conversion app at this point. 

Two suggestions:
1) add force per length (lb/ft to kN/M) as this is something made by a company selling to structural engineers. 

2) add some sort of favorites to allow quick access to the conversions I use most.
