Explain the problem as you see it
There needs to be some basic file storage available in order to become an all-in-one productivity solution for teams.
When working on certain types of project, one needs to be able to add documents into records (i.e. nodes), e.g. a contract PDF.
This is particularly important in a collaborative environment, e.g. a marketing team working on a campaign needs to be able to access media files.
Why is this a problem for you?
I recently worked with someone on a collaborative project, and the other person was using Apple's Hook Productivity to add links to documents. This made me realise that we would have to have a joint storage solution (e.g. Dropbox / GDrive) if we wanted to work on the same files, which would be another SaaS expense (although admittedly, one that most companies would have - still, it would mean leaving the workflow to access another program).
At the moment, one can insert images, but accessing the original image file is cumbersome.
Suggest a solution
A field type for attachments, similar to Airtable, which enables you to add attachments that are easily accessible directly in Tana.
