Usability problems in stock_inventory_barcode

[zeroheure]

I'm currently using stock_inventory_barcode to help my wife with her inventory which is around 3000 different products in 3 places. She is scanning and I am in front of the screen, tabbing from field to field in stock_inventory_barcode wizard.

I have quickly enhanced the module UI to reduce tabs key and dismiss some errors. So this bug report is about the use of tab keys to go in a field and about errors that can happened. Obviously this is keyboard driven. I am currently using the 10.0 version, but problems are the same in 14.0 :

• It is faster with focus on the product_id field. User quickly learn how to deal with some inconvenient of the Many2One field.
• It is easier, faster and error prone to have field add_qty before change_qty because:
  • the most common case after scanning is to tell the operator how much products there is to add
  • currently, the operator can accidentally erase the previous recorded quantity or add to much products if he type the new number next to the previous one instead of replacing.
• there is really a need to focus the input at wizard launch on the first needed field (product_id or product_code), just use stock_inventory_barcode module with web_dialog_size module installed and you will understand (at least in Odoo 10)...

Using product_id to search for barcode creates another usability problem:
In product_id field, current barcode search works with exact match and is case sensitive. This is wrong because in retail industry not each product's variant own a barcode, sometimes variants share the same barcode. In this common case, retailers around me simply add a letter after each product barcode to differentiate variant (for example B for blue, G for green, etc.). Odoo POS works like a charm with it. But not stock_inventory_barcode.
