Walkthrough

The Time Settings page now allocates timer indices by checking TG tbody elements. It reuses indices after row removal, enforces the configured timer limit, and scans existing rows to update timer settings.

Changes

Timer row management

Layer / File(s)	Summary
Timer row DOM lifecycle wled00/data/settings_time.htm	Timer rows use TG tbody elements. The page finds the first free index below maxTimers and removes rows by their TG id. The add button displays “+”.
Expanded rendering and timer scan wled00/data/settings_time.htm	rTOPO() and Wd() scan existing TG elements. Wd() writes weekday values to WV inputs. Preset placeholders display “Select preset”, and expanded sections contain the separator row.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to bb1fa

Removing and re-adding a timer can change the saved order, and screen-reader users may not know what the plus button does. These are bounded issues; preserve timer order and give the button a descriptive name.

- Line 97: Update addTimerRow() and the removal flow around rTR() so adding a
timer reuses an available index from T0 through T15 instead of relying on the
ever-increasing timerCount. Preserve existing timer groups and ensure newly
created groups remain within the WLED_MAX_TIMERS range.

- Line 458: Update the button that invokes addTimerRow() to include the
descriptive accessible name “Add Timer” via an aria-label, keeping its visible
“+” and existing behavior unchanged.
- Around line 95-99: Update the timer-group insertion in addTimerRow() so a
reused lower-index group is inserted before the first existing group with a
higher TG index, appending only when no such group exists. Preserve ascending
numeric order in the DOM.
