- (2025-08-05) James Nolan: Pretty raw at the moment but hopefully can improve. 1) Biggest issues is that after I click the icon, I want to start typing a calculation on the number pad straight away. But nothing happens. Because you need to click on the calculation line BEFORE typing. Didn't happen with cloudy calc and an unnecessary step slowing me down. 2) Put in 6.15*3/2 and it shows 9.225000000000001 Must be how it's using floating point numbers but not ideal...
- (2025-07-19) Michael Murphy: I haven't found anything else this close to the old cloudy. Thank you. I haven't yet been able to figure out the usefulness of the multi-line entry option. Please post an example of its usefulness. I also think it would be better if the cursor was active in the data entry field upon opening of the extension. My poor old eyes would a love a font size option.
- (2025-07-18) Adam Murphy: Thank you so much! I use it for simple accounting, but having the history of your calculations means I can save a heap of time, and remember calculations from a prior days.
- (2025-07-17) Evgeni Stavinov: Great replacement for the Cloudy Calculator. One feature request is to have a tooltip or a small page with examples how to use the multi-line mode. I needed to browse the source code on Github to determine that Ctrl+Enter evaluates multi-line expressions. Simple Enter is for single-line ones. Also found that multi-line is not for a very long single expression, but for multiple expressions that are evaluated all at once. Nice work!
- (2025-07-17) Ezra Shapiro: Thank you so much for doing this! Can you please make the it so that if I click on Nimbus, I can immediately start typing numbers? At the moment, I need to click once on nimbus, and again in the field to start my calculations.
- (2025-07-13) Tom Harrington: Finally a perfect replacement for Cloudy. 5 stars isn't enough!
- (2025-06-15) Rajeev Agrawala: I had been missing cloudy calculator so much. Love this one. It also has variables and equations. Not a big equations user, but ability to save variables and reference them is tremendous.
