Hello Alex

Thanks for posting in the community! While there is not a limit to the number of page tabs you can add to a document large documents or documents with many page tabs (dependent on the size of the diagram on the page) may have trouble loading or may run more slowly than documents with few page tabs. To keep your diagrams in one place while ensuring they run and load with the best level of performance I recommend creating a folder for your process diagrams. This will allow you to access these diagrams easily while ensuring the documents do not become too large. Hope this helps! Please let me know if you have any additional questions!
