Hi @moerah ,

I have a style Table Variable in every app I do and have not noticed anything in performance penalties. Almost every control references it in multiple parameters directly or indirectly. An example is below

Set( gblTheme, { Dark: RGBA(30, 65, 144, 1), Lighter: RGBA(32, 162, 229, 1), Light: RGBA(18, 174, 196, 1), Hover: ColorFade(RGBA(30, 65, 144, 1), 95%), Shade: ColorFade(RGBA(18, 174, 196, 1), 85%), Press: ColorFade(RGBA(30, 65, 144, 1), 30%), lFont: Font.'Open Sans Condensed', tFont: Font.'Segoe UI', lSize: 13, tSize: 11 } );

This also allows the very rapid change of anything throughout the app.

Using variables for text colors, text size, and other properties can improve the performance of your app in some cases. Variables are stored in memory and can be accessed very quickly, unlike data from cloud sources that require connector calls and network latency. Variables can also help you avoid repeating the same formulas or values in multiple places, which can reduce the complexity and size of your app.
However, using variables also has some drawbacks. Variables can consume memory and affect the app’s loading time, especially if they are large or complex. Variables can also introduce errors or inconsistencies if they are not updated or cleared properly. Variables are also not supported by delegation, which means they cannot handle large amounts of data from cloud sources.
Therefore, you should use variables wisely and only when necessary. Some best practices for using variables are:
Use global variables for app-wide settings or constants, such as theme colors, user information, or app version.
Use context variables for screen-specific settings or temporary values, such as filters, selections, or states.
Use collections for storing and manipulating data in memory, such as offline data, user inputs, or intermediate results.
Use the Set, UpdateContext, and ClearCollect functions to create and update variables and collections.
Use the Reset function to clear the values of input controls and variables associated with them.
Use the Clear and ClearAll functions to remove variables and collections from memory when they are no longer needed.
