    Download cannot be prevented. When viewing anything online it is always downloaded to the user's computer and read locally. Only difference is that using a web browser the document is read from browser cache.

    I love using this plugin so I don't have to convert the PDF to an image to put into a lesson. The plugin is just really slow when viewing PDFs.

    if we add pdf of more than 100 pages (of size > 30mb) then it is taking too much of time to load, can we have any option to improve the performance.

    The performance issues are just on the first view, after that it should be cached.
    I'll check big files.

    Performance is now much better (on version 0.99), cache is automatically created via adhoc task on module creation, module update and first view after cache purge.

    Thank you for creating an amazing plugin for Moodle, Yedidia. The only things colleagues would like is the "search" feature available on a PDF file.

    Thank you for this plugin. Is there a way to control the size of the window in which the pdf is displayed? It is quite large now for our screen and requires using a scroll bar.

    I have installed the plugin and upload a 36 MB file. Right now my host space is full. How I can delete the uploaded file?
