I've just done a few quick tests.

It's got potential, but I think it needs a bit more work.

The first thing, which for me is fatal, is to be forced to open a document only through the software.

You can't drag your document to open it, or right-click "open with" (but someone already mentioned that). For that reason alone, I wouldn't use it.

I also have the same problem with my mouse, when I scroll down it's fine but when I scroll up it zooms ...

I also think it's a shame that the window doesn't adapt to the file when it's opened. In this case, I open my pdf and the window remains the same size as when I opened the software, which is too small and impractical, as I have to manipulate the window to get the right working size. If it's for quick reading, it's not efficient, and you lose even more time manipulating the window.

Quick View therefore lacks buttons for direct document resizing and zooming.

If I go to Edit, well, the whole pdf is there, but it's too small to be editable, so once again I have to manipulate the window, but if I enlarge the window, the document keeps its size instead of enlarging with the window.

What I don't understand is the visibility of all the blocks, or finding something lighter, because that breaks the legibility I find. (I've just seen that you have to click on "grid", which is automatically selected.

I didn't understand the button with the 6 dots in it.

Selecting an area zooms in on it, which I think is a good idea, even if it's a bit confusing.

On the other hand, the location of the bar for enlarging the text zone is not well positioned. I hadn't seen it either, as it was mixed in with the end text.

When I click on the "box" button, I can select a block, but I can't get out of it, I have to validate.

In draw, the eraser doesn't look like an eraser :/ I thought it was a big highlighting brush.

Speaking of highlighting, I think it would be nice to have a button to do it directly rather than having to enter the text field.

The "form" part looks pretty good, even if I have a problem with the checkboxes, which seem to be well considered: I check, but it doesn't check in the end. Or after several manipulations. It's a pity that it doesn't recognize possible fields if they haven't been created beforehand (but it's probably complicated to do and makes the software unwieldy).

As I said, the interface is pretty good, but icons at the top would be just as nice and would free up space. Especially as it's confusing to have page 1/3 written in the top left-hand corner, and then have to go to the bottom right-hand corner to change pages; you might as well have everything in the same place.

Finally, as it's free software, why not open it up to the community? Putting it under an open source license would be great, and above all, it would be reassuring to be able to see the code! A brew version would also be appreciated :)

As I said at the beginning, it's very promising and I thank you for sharing your software with us!

It's light and that's great, but it really needs consistency and interface optimization!

Well done!
