We convert LEADS to ACCOUNTS and CONTACTS.
In the leads we map the "Company" field to "Account Name" (within the accounts module)
I would love to name the lead field "Account Name" so it matches the same field in Accounts. I've had to explain the difference hundreds of times... and I even have tooltips explaining issue.
Summary:
Please let us rename the lead "Company" field to whatever we want OR assign it a name based on the Account module ie: Account Name. Would be a simple but huge usability improvement for us!
