Firstly, is there any way that I can specify a specific width for the column as when I list multiple numbers, the Description column (located on the LHS of the Serial Nos column) shrinks and becomes extremely narrow.
possible by use of custom themes. read below for ideas.
you will have to customize your theme for this.
proceed only if you are familiar with html coding or else hire someone locally to do it for you.
follow the steps provided in the below post.
in the above post, replace the word HSN in the provided code with the column heading Tax Code.
make sure your column heading matches exactly. even a small change in letter case will cause errors.

My second question is to ask if there is any way that a search can be carried out for a Serial Number that is listed in this new custom field or alternatively, if I change my system and list serial numbers elsewhere on the invoice (possibly in the Description Column or in the Notes panel, can a search be done that way ?
if you have set the custom field to show as a column, you can use the Search function provided in the invoices list page.Sales Invoice Totals by Custom Field under the Reports tab.
