small improvements ideas on databag

# Improvement Suggestions for Databag Hello, First of all, thank you for this project, which I find very interesting and promising.\ I had used Databag some time ago, but back then I found it a bit complex to set up, especially due to hosting requirements and not having a homelab.\ Now, with a functioning homelab and particularly in the context of recent European announcements about potential backdoors in messaging apps, I am revisiting Databag with great interest. Here are some feature ideas and improvements that could enhance the experience: ## Proposed Improvements - **Upload and Download Progress**: It would be useful to not only have a progress bar but also having indicator when sending files, like a percentage or an eta. - Similarly, when downloading a file, showing more details (size, estimated time, progress) would be helpful. <img width="171" height="162" alt="Image" src="https://github.com/user-attachments/assets/00876b83-2f5e-46e8-bda6-abd5764c0e66" /> - **Web Interface Customization**: Allow administrators to customize the web interface CSS directly from the admin settings to adapt the server appearance to their preferences (this would be more difficult for mobile apps). - **Voice Messages**: add an option to send voice messages in subject, just as files but directly integrated. - **Simplified File Attachment**: Instead of having to choose between "attach image", "attach video", "attach audio", offer a single option "Attach Document" and let the system automatically determine the type and preview. This would make the interface clearer. <img width="251" height="136" alt="Image" src="https://github.com/user-attachments/assets/6b0253ee-da9d-480c-a035-fc71af42d620" /> - **Emojis and GIFs**: Add the ability to insert emojis and GIFs in messages. For GIFs, the Tenor API could be used to easily search and include animated GIFs. ## Conclusion Thank you again for this project, which provides a privacy-respecting alternative.\ These suggestions are just ideas to make the experience smoother and more enjoyable.\ In any case, I am glad to see Databag continuing to evolve!
