Hello. I recently switched from the trial to the paid. Here are my suggestions:
1) Make the font size to be selectable of the user interface, just the whole overall user interface where dinky text is. The font size the program is set it is dinky, and for some things I have to use readers (i.e., readers are reading glasses that act only as a glorified magnifying glass because they're not actual prescription eye glasses), then sometimes combined with a separate magnifying glass I'm holding up to my computer monitor. I've attached some pictures of examples of what I mean that I took with a camera instead of just doing a screenshot with a graphics program, because a camera is looking at the monitor just like the eyes are. I've also attached a text file with HTML/Javascript/CSS code as a very simplified example of what I mean since this is something I'm doing for the site I'm developing, which is to let users take notes of what they're reading. This file can be renamed to be HTML and then opened as-is in your browser, and it shows a textbox for users to type in their notes and then save their notes to a text file, but it also allows the user to select their own font size out of a few I've thought to be enough variety (I hope anyway). I think it would be greatly helpful if this same functionality were applied to the font size of the user interface of Site Designer (as well as all other programs that have this same dinky default font size).
2) When a person already has the trial version installed and they're then installing the Full/Paid version, the installer program should recognize the folder where the Trial is already installed and let that be the initial default instead of the standard usual folder of "Program Files". I use custom folder names such as "Multimedia" & "Internet" & "Word Processing", and for Site Designer and anything for web development, I have a folder named "Prog'g" (which is just a short spelling for "Programming").
3) Increase the length of time for the trial, even if just a week. I have busy involved days and wasn't able to finish my testing and experimenting of the trial in time for the expiration. However, I was fortunately able to get figured out something that had me confused which then opened up being able to understand how that part of Site Designer works.
Thank you and have an awesome week, I hope these suggestions will be worthwhile to consider.
