Hi all! Thanks for your questions!
The new features should now be available to all users in Project for the web. Check your task details to find the 'Add attachments' button.
Thanks for your feature requests! We love to see your new ideas. I would also recommend submitting these thoughts through the in-app Feedback button that we have. This will help us if we have further questions about what exactly you would like to see in Project for the web.
Fsarmiento The Quick look column shows icons that represent different entities on your task that don't have their own column. For example, before this column, there was no grid indicator of which tasks did and didn't have notes. You can now see which tasks have these entities. We hope to expand on this in the future to make it even more useful. Please let us know what other information you would like to see here!
Thanks!
