# Tutorial improvements.

## Replace ">>>>>" with "<<<<<<"
- To better visually indicate the direction the user should swipe. Maybe I'm the only one dumb enough to look at the > arrow and swipe that way, which gets you nowhere.
- Ran into a bug here when literally typing in "<"
````The value of attribute “android:text” associated with an element type “TextView” must not contain the '<' character```
- Fixed with the help of [this thread comment](https://stackoverflow.com/a/40971204/22771801).
Change the id to match the respective arrow direction (was '...right' is now '...left').
