Did a Forum search and did not see this specific feature request - apologies if I missed it or if it's a current setting feature I've overlooked!
For manual work unit additions, suggest having End of Work automatically adjust to the Start of Work time once that time has been set/saved. Would save time manually scrolling to move the End of Work beyond Start of Work. Provides a bit of time stamp validation as well. Thank you for considering.
And I love this app - very well designed, a great bargain!
