Well noted! Thanks for sharing, Olly.
Persisting column width is actually something our team has been looking into lately. Glad to know we’ve got +1 interest from you 
Can I confirm quickly that you are using our Dashboard 3.0, or the latest Canvas Dashboard, Olly?
Also, may I ask why you would like to persist the column width? Is it because you can still see values being cut off sometimes? Or you’re more interested in the freedom to adjust spacing, excel-like?
