Make improvements to Excel bookkeeping spreadsheet

I’m looking for an Excel expert.

I designed a very simple bookkeeping spreadsheet many years ago.

I need this bringing up to date. Things like adding a button to add more rows for example. And also a button which will remove nil rows on the profit and loss.

I’m sure you can do a much better job than mine. You can view the spreadsheet here - https://www.dropbox.com/s/6d2r702pnndcfs6/2019-03-18%20-%20Cash%20Book%20Pro%20v1.xlsx?dl=0

The budget expects many improvements and design improvements too.
