Thanks for playing and sharing feedback!
The initial, interactive tutorial is deliberately limited to the most essential tasks. It was a delicate balance between covering the essentials and not overwhelming the player with too much at the start. If you go to Tutorials in the Options menu, there are more details available about several other things not covered in the initial tutorial. The Controls menu also shows you what buttons to press for everything. If I remember correctly it's B to open the redecorate menu.
I'll work on the event tooltips and controls some more! The asset pack is the Modern Exteriors/Interiors/Office pack by limezu :)
