Matt I think it would be a good idea if we shortened the width of the "fuel used" and "Cost of fuel" colums and gave that extra space to the "Notes".
This is because the NOTES column is the one that has the most input from our users. The Fuel columns are longer than they need to be even for users who note down numbers to a few decimal places. That wasted space can be well utilized in the Notes column.
When viewing ones gaslog and comments, a typical page that shows 10 entries in one window may now show 15 entries as the Notes column is usually the one that uses the most rows. We can significantly reduce the number of rows required for Notes entries, especially for entries like mine, where the owner is one who likes to overexplain and share every detail as to what he did to achieve the latest set of numbers
Hope you take this into consideration.
