Hello everyone, I was working on this app lab turtle only drawing program. I had a few questions about how to fix some bugs, and what else I should add, suggestions, etc
Question 1: How do I fix page unresponsiveness and aw snap issues on low-powered devices, like my Chromebooks? I’m guessing I’m supposed to split the task up into chunks instead of going all at once, probably using delays, but not sure if that will work. I experienced page crashes and slowdowns in the late 2000s, 5000 - 30000 instruction mark.
Let me explain an “instruction” in my project. My project has a save/load drawing feature, JSON raw, and App Lab optimized, an instruction as a unit is well… an instruction like moveForward(5); , that is an instruction, about the same for json just a different design. So I was wondering if there is any way to fix page crashes with big instructions?
Question 2: What other features should I add that are not very time consuming to build? If I wanted to build time consuming, I might as well build v.3 after I finish v.2, like layers and macros, and draggable gestures like screen zoom and pan (there are buttons for zoom and pan currently in my project). Also, the UI of my projects is cluttered due to being an App Lab screen 
Question 3: Are there any other suggestions to add, anything to change? Please give feedback if you have time to test my project. I don’t have playtesters and don’t have the time to playtest myself, as in v.1 of the project, which was finished about 2 years ago
