Certain actions are freezing the UI. I don't believe our async/await is working properly.

We should have it on its own thread or at the very least don't freeze the UI when a PDF change is in progress. This effect is most noticeable on upload, import, and viewing the document colors.

The color filter needs a way to narrow the selection. I think it will need a custom filter. Alternatively, we could try to utilize the tag selection filter.

• Search only on page range
• Skip/limit ?

Some PDFs throw a null arg exception when the PDF is saved. This mostly seems to occur on PDF versions older than 1.5.

I can make some of them work in a blank iText project, but others don't work at all.

One possibility is document corruption. However, those that work in a normal iText project would not have that issue. It might be something with the way we use streams to load the PDF reader/writer.

Several of our components have gotten rather large. A few are several hundred lines long!

We should use the code-behind approach (separate .cs file for logic, .razor for UI).
