To further enhance the modeling experience, particularly for new modelers, having a hovering tool tip when typing parameters within a function would be useful. It could be structured such that after typing the start of any function, a hovering display lists the required/optional parameters needed.
As an example, typing "Find()" would result in a hovering "FIND(Text to find, Text to search [, Starting character])" display above the cursor. This would lend to accelerating the learning of those just beginning their modeling journey, and increase overall experience.
When working with others new to the platform, it is not uncommon to see the formula editor reject the formula due to something as simple as flipped parameter order. Having a tool tip similar to the above could help alleviate this, and avoid increased troubleshooting time.
