I thought I only needed this temporarily I thought I only needed this for an isolated use, but found it was much more useful in future applications. I appreciated it in a pinch.

Very good to be able to edit pdfs Very good to be able to edit pdfs, though it is still a fairly clunky procedure. But for a free download you can't complain.

cancelled as a gesture of goodwill I downloaded the software and although it has a lot of good features, I didn't really need it. I thought I had cancelled right then, but I haven't found any more mail from me. Now the annual amount has been debited and I have contacted their support. After I explained that I didn't actually use the software, the subscription contract was subsequently and I was refunded the amount.

What do you like best? Able to quickly modify documents and create professional presentations. What do you dislike? Can't really think of any negatives. Maybe wish it were free. What problems are you solving with the product? What benefits have you realized? Easily convert invoices into delivery tickets. Cuts down on time spent creating documents.

So far so good. I like the friendly interface and the different options of sending processed files. I would like to request developers to incoporate "rotating page" for some documents that may be uploaded upside down

An application stack is a suite or set of application programs that help in performing a certain task. Many office applications include word processing, spreadsheets, databases and email utilities in one application stack.
A technology stack, also called a solutions stack or a data ecosystem, is a list of all the technology services used to build and run one single application. The social site Facebook, for example, is composed of a combination of coding frameworks and languages including JavaScript, HTML, CSS, PHP, and ReactJS.
Stack. In computing, a stack is a data structure used to store a collection of objects. Individual items can be added and stored in a stack using a push operation. Objects can be retrieved using a pop operation, which removes an item from the stack.
A server stack is the collection of software that forms the operational infrastructure on a given machine. In a computing context, a stack is an ordered pile. The server stack may also include server software for various Web services.
A Tech Stack is a set of tools that are used to construct and power an application. It consists of a combination of software applications, frameworks, and programming languages that realize some aspects of the program.
A top voted answer on Quora explained that what is a full stack developer: A full stack developer is an engineer who can handle all the work of databases, servers, systems engineering, and clients. Depending on the project, what customers need may be a mobile stack, a Web stack, or a native application stack.
Full stack development: It refers to the development of both front end(client side) and back end(server side) portions of web application. They work on the frontend, backend, database and debugging of web application or websites.
If you already have experience of working on back-end development, learning front-end development takes 46 weeks. So you can assume that to become a full-stack developer it would take anywhere between 812 months depending on how proficient you are coding and how quickly you learn and other basic computer stuff.
