We use it on several sections of our smartsheet and we wish we could make this symbol larger or have a way of changing the size. A lot of our users say they find it hard to see and then we get missed updates from them not realizing they need to open a section.
We would like not to have to put Open in a cell nearby just for them to realize.
Another example for you to see the way we use smartsheet to function.
Not sure how it works or if its a coding thing.
Edit* We understand they could zoom in but our sheets can get long and it just would make things more difficult to fulfill updates if they have to zoom in and out for full context in relation to their updates.
