Are you planning on adding support for password protected spreadsheets?

Thanks.

No. We don't have such a plan because we don't have enough information on this issue.

When do you plan on implementing custom Exception classes so developers can better handle problems that arise?

We are doing it. An ExcelException class is added to Aspose.Cells and we are porting current exception handling code to this new Exception class.

Is there any chance you can include an ImportHtml feature into a cell? This would allow a complex datatable with headers, templated columns, spanning, styles, etc (or any other custom control that can be rendered to basic html with a text writer) to be placed onto a spreadsheet.
To see an example of this in action, copy a grid from a web page and just paste it into a cell within excel. It automatically splits out into relevant columns and takes on the appropriate formatting. I would really love a programmatic way of doing this...
Thanks

ImportHtml is really complex. We did think of that very early but still need investigation. It may not be available in a short time. I think we can start to make it at the end of this year.
