Consider adding invoice customization. Here's a great framework: https://github.com/Invoicebus/html-invoice-generator
Client Welcome Page
Add a client welcome page where we are able to add checklists or forms that the customer will need to complete.
Custom email options
1) Customize email notification content (including branding) 2) Ability to send notification emails directly from your own email address
Ability to add SMTP login details so outgoing mail can come from our own servers instead of showing project.co details.
Move to a single page app framework
We are planning to rebuild the front end of Project.co in a single app framework such as Angular or React. This will provide improves navigation throughout the system and an improved user experience.
Along with logging the time worked, I would like to the timer to take screenshots of the users desktop. This is an essential feature for remote team and is standard for freelance market places.
Ability to reorder lists
It would be useful to be able to reorder the lists in projects, people and companies etc by clicking on the header row of the table. When you have a long list it is harder to find what you need.
Use electronic signature that you can use to sign documents. Track date & time. Payment integrations included.
