It would be nice if we could upload files that are linked to the client.
For ex. license plate, driving license, ID, and so on.
Maybe this way:
by clicking on a specific client, the window opens and you see four sections:
Details | Quotes | Invoices | Payments | Uploads
The Upload should not be limited by filetype or it should be possible to edit the file type limitation in the settings. for. ex. pdf, jpeg, png, docx, xlsx, should be already enabled and we can simply add new file types by entering them in the existing list.
The interface could be very simple:
Filename | File type | File size | Uploaded by | Date
Also it should be possible to delete and lock the files (a keychain icon would be fine)
