Thanks for the idea.

I have tried Avidemux already, it surely is powerful, but the UI is rather "old", in the same way than Shotcut, etc.

I was looking for someone more modern, a bit like the TikTok app editing feature which is really great (except you cannot export to MP4 at the end, save a project, for future modification...)

The best for small videos would be a simple UI with Text, Media... (left column), timeline (bottom), and export button. Not much more. Here it's a screenshot from veed.io but the pricing is really too high (15$/mo is more than 500$ in 3 years): https://veed-assets.b-cdn.net/images/Webflow/legacy/6026a6dc...
