Double-Tap: Restart to Step 1
New in 1.1.2
Double-tapping the Play button restarts the pattern from step 1.
- While playing: playback keeps going, but jumps back to step 1.
- While paused: the playhead resets to step 1 and a "stop / reset" tooltip confirms it.
- In a WiFi jam session: the restart syncs to every connected player, so the whole session snaps back to step 1 together.
A single tap still toggles play/pause as normal — Pixelboop waits briefly to see if a second tap follows before acting.
Hold for WLED Config (Shortcut)
The primary way to open the WLED config dialog is to tap the WLED Rainbow button on the bottom control bar (row 23, cols 0-3). As a power-user shortcut, you can also hold the Play button for 3.5 seconds to open the same dialog. Both let you:
- Enter WLED device IP address
- Test connection to LED strips
- Configure external lighting
See the WLED Setup Guide for complete LED strip integration instructions.
