IMHO now that the Manage Shipping Methods and Shipping Methods Restrictions have been integrated into the Fixed Rate Shipping and Shipping by Weight providers, it makes no sense to keep Fixed Rate Shipping since:
- It can be configured with the Shipping by Weight provider: just apply the rate in the first term of the formula (Formula to calculate rates [additional fixed cost] + ([order total weight] - [lower weight limit]) * [rate per weight unit] + [order subtotal] * [charge percentage])
- In this way it can also be configured by store, warehouse, country/state/zip, etc.
Furthermore:
- It is very confusing and difficult to navigate, to now have the Manage Shipping Methods and Shipping Methods Restrictions as tabs, but when you are in any of the two the tabs are not available and you cannot go to the other option or to the configuration of the shipping method provider.
- When adding/editing new records there is no contextual help and in some cases it might difficult. For instance in the ZIP field it is not clear if you can set several ZIPs separated by coma or if you can wildcard signs.
