When making changes to an app, I sometimes find myself having to update multiple expressions - particularly those used in constraints such as "Show_If" and "Editable_If" - to integrate the changes. This usually involves going through columns one-by-one and pasting a new expression in the appropriate constraint field.
I'm suggesting each project has a "Constraint Expression Library". Entries in the library would comprise:
1 - An Expression Name (to be referenced by the column constraint);
2 - the expression itself;
3 - A description/explanation of the expression)
When setting up a column constraint, the developer could reference a Library Expression Name instead of rewriting the expression. Then, when an expression is updated in the library, those updates flow through to constraints referencing it said entry.
(Similar idea to calling a function to perform a task, rather than rewriting code every time you need it)
