Hello everybody !
I have been developing a software using Matlab App Designer for 2 months, and while my code grows up (~9k lines today), App Designer editor takes more and more times, even for simple tasks, like writing a piece of text, or make a line break...
I tried to untick "Enable app coding alerts", without noticing any significantly change...
I don't have choice to edit my code in another text editor and paste it in Matlab AD..., which is not convenient...
Do you guys have any idea to fix out this issue ?

9k lines are too much in one script. I have a good suggestion.
Try to break down the designer script into some functions and write them in separate .m files and use function calling in designer script.
This makes app designer more efficient.

Hi Robin,
If possible, please update to release R2020a where this has been significantly improved. You can read more details in the MATLAB Release Notes here:
and search for "App Designer" under the Performance section of the R2020a release notes. Switching to code view, typing, entering new lines, etc., have all been improved.
Thanks,
Jared
