@JohnsonJunSheng Great work, I have review the app and saw good improvement in UI, below is my feedbacks:

1. Performance of the app: after I uploaded the csv file, the preview table beside pop out quite fast, but when I navigate to "Simulating" tab, the graph & table spent around 5-6 second to render, which I think the wait time is unreasonable, since we dont have large data & complicated calculation.

For improvement, you may google some performance tips for R programming, & shiny, here is my recommendations:

• https://appsilon.com/speeding-up-r-shiny/

2. Graph & table UI look, I think the table can be design nicer, eg, thousand separator & column names

For graph, maybe the y-axis can be formatted?

Other than that, i think the rest are good!
