Moritz Warning	43f0519487	LunaEvent: rework sleep event Remove adjustment buttons and simplify design.	2026-02-12 23:01:01 +01:00
Moritz Warning	1bcfc18a71	MainActivity: rename datepicker	2026-02-12 23:01:01 +01:00
Moritz Warning	e345e98668	layout: replace menu icon with utf8 character The three dot menu icosn looks odd when stretched due to the dynamic menu feature. Thus replace it with the hamburger menu character that looks better when scaled.	2026-02-12 23:01:01 +01:00
Moritz Warning	09f5a4e27b	MainActivity: sort events before saving Also replace notifyItemInserted since it does not call the adapter to redraw the row striping when a new event is added.	2026-02-12 23:01:01 +01:00
Moritz Warning	b3b432525e	StatisticsActivity: rework all statistics Improve the overall code.	2026-02-12 23:00:58 +01:00
