# Objective
Make it easier to check if some set of inputs matches a key, such as if you want to allow all of space or up or w for jumping.
Currently, this requires:
```rust
if keyboard.pressed(KeyCode::Space)
|| keyboard.pressed(KeyCode::Up)
|| keyboard.pressed(KeyCode::W) {
// ...
```
## Solution
Add an implementation of the helper methods, which very simply iterate through the items, used as:
```rust
if keyboard.any_pressed([KeyCode::Space, KeyCode::Up, KeyCode::W]) {
```
# Objective
- Remove all the `.system()` possible.
- Check for remaining missing cases.
## Solution
- Remove all `.system()`, fix compile errors
- 32 calls to `.system()` remains, mostly internals, the few others should be removed after #2446
This is extracted out of eb8f973646476b4a4926ba644a77e2b3a5772159 and includes some additional changes to remove all references to AppBuilder and fix examples that still used App::build() instead of App::new(). In addition I didn't extract the sub app feature as it isn't ready yet.
You can use `git diff --diff-filter=M eb8f973646476b4a4926ba644a77e2b3a5772159` to find all differences in this PR. The `--diff-filtered=M` filters all files added in the original commit but not in this commit away.

Fixes#1895
Changed most `println` to `info` in examples, some to `warn` when it was useful to differentiate from other more noisy logs.
Added doc on `LogPlugin`, how to configure it, and why (and how) you may need to disable it
