It is a simple enough question and in fact MCXU (10.3.0 2200) tells you this on the welcome page
Disabling this Welcome PageTo disable the display of this page when running MCUXpresso IDE in future, untick...
- Preferences -> MCUXpresso IDE -> General -> Show Welcome Page
Sadly there is no "Preferences" menu or submenu.
The Help file says the same thing
Chapter 3. IDE Overview
When MCUXpresso IDE is launched, a Welcome page is displayed (usually within the Editor view). This page contains product information including a link to the User Guide. If this page is not required on startup, it can be disabled via unticking the preference at Preferences -> MCUXpresso IDE -> General -> Show welcome view.
But the image above that tex shows a "Show Welcome Page" item
But clicking it does not seem to disable the welcome page
Any other suggestions?
It also seems that there are a few trivial bugs that can get fixed...
