I have been using the leads feature for about a week now and keep on hitting issues where I want to interact with the lead in the same way as I do deals. Some examples

Be able to see contact name and company in the summary view

Be able to enter the contacts job title 


As a summary I like the idea of treating enquiries as leads but personally I am struggling to understand why the user interface and functionality needs to be different. For me it would be better to treat them in the same way as deals but just exclude them from the deals analysis
