I would love a notebook/notepad that would have a translucent/transparent paper choice. This would allow me to have whatever application, email, PowerPoint open in the background and then I can take notes on top of it. Versus having to import into the notebook. It could be slightly dimmer or similar so that you would obviously know the application was running.

when i need to send some of my ideas to another person, an export as pdf for all or selected pages would be great to attach to a mail.

I added emojis to a few of my notebook names, and they all became corrupted. Is there a way in which I can delete the emojis from names? Could you guys fix this issue? I think many of the can't be opened issues are coming from naming the notebooks with emojis...

I think actual pen lag is about the same in Plumbago and OneNote, but more noticeable (and therefore distracting) in Plumbago because in drawing/writing mode Plumbago shows a "mouse pointer" whereas OneNote shows a "pen dot." Of course any actual reduction in pen lag that can be achieved by hardware or software improvements is also desirable.

It would be great if you could drag and drop pages to reorganize

Add a drawing tool which allows the selection of a symbol from a library of symbols, eg flowchart shapes, engineering symbols, furniture, or pretty much anything users could dream up. It could be as simple as a appdata directory with sub directory for each library and bitmaps for each symbol. An enhancement would be the ability to save symbols from Plumbago too. I luuuuv this app already!

place 3 off-hand fingers on the screen to make a ruler appear for drawing straight lines. would be awesome to be able to do scaled drawings.

"The content of this file appears to be corrupted and could not be opened" this event happen? and How can I fix it.

Even just 2-3 layers would be nice - like using tracing paper to explore drawing options without having to cut and paste onto multiple sheets.

With the Surface Pro 3, I'm using the Surface Pro 4 stylus (pen). Even when I set the smoothing to 1, there is a serious lag in the handwriting, and the app does not always "print" my handwriting accurately (e.g., the "circle" a g or a is often squished and non-circular, even though I make an effort to write it correctly. I'm going to continue to experiment with this, but so far it's a pretty serious problem.

Add pressure sensitivity to the pen tool akin to the available feature in Windows Journal.

Now the pen cursor is an arrow. It would be great if we can select several types of cursor like a pen, a cross, a circule with a point inside, etc

Continue to support this app or make sure I can export the notebooks into a common format (like pdf)

Continue to keep it simple (in spite of all the suggestions to add features) Send those folks to OneNote.

Add 3D animation (just kidding)

I don't know that the Plumbago is compatible with Chinese characters. I'm a Chinese.

External monitor (connected to SP4) messes up page layout (background is only partly shown)

When you share a sheet, Plumbago sends a screen capture, with the side menu and the color&pen palette on it. Both must not appear on it.

resize screen, resize images, context sensitive right click
