Avaza has had really nice task Kanban & List views for a long time.
It has the combined functionality of Asana + Trello + Harvest + Freshbooks in one seamless product.
The public sales site for the app was using a popular wordpress theme with that style. The styled scrollbar has now been removed in the interest of the more familiar scroll experience.
Tim, Co-founder Avaza
We've just launched Avaza, and look forward to HN community feedback and suggestions.
Avaza is designed for client-focused businesses such as freelancers, consultants & professional services companies.
The modules for Project Management, Timesheets, Expenses & Invoices can be used together or independently to suit your needs.
Everything in Avaza is responsive, so you can get a fair experience on all your devices. Yes even creating invoices on your mobile :)
