Unclear as to whether or not I can save multiple versions of the fillable form for future editing, which I assume, but it's not intuitive, otherwise I would have rated 5.

difficult to sign and other parties not knowing the software, I feel I need to be cautious. Too costly for a novice one time user. Overall, it has been helpful. thanks!

It's been great so far. I need to learn how to move around the dashboard quicker. Also, I need to learn how to set up individual folders (if applicable)?

Ny experience was good but I only have a need for the... Ny experience was good but I only have a need for the form I used maybe once a year. So I will probably be canceling my month to month once I am sure the form I needed has been accepted. It would be nice if you had an option for a subscription that was based on usage rather than on time. I might then sign up for a longer term commitment if I wasn't being charged every month but rather on my usage. My experience with your product was that actually filling out the form was user friendly but it was a form that had a continuation sheet and figuring out how to use several continuation sheets was not intuitive and I ended up filling out several different form continuation sheet pages and then had to combine all those multiple forms into one document in order to get what I needed for submission to the court.

It's essential for digital nomads It's essential for digital nomads. Since my base is in the US. I rely on these solutions to continue operations in the US from abroad. I would integrate payment systems, especially with the banking networks to be able to send money orders or checks physically. And I would suggest connecting with virtual offices to be able to interact with clients in a virtual office setting. I'm thinking a virtual secretary solution... just some thoughts to improve. Abe

Very easy to use Very easy to use. Loved it. Struggled with editing sideways orientated text. Type replaced went a little wonky, it was for a quick edit to a a basic document, not an official presentation, in which case I might have required a more powerful editor.
