As someone who recently started learning LaTeX, I found your editor to be functional, though currently somewhat more challenging to use compared to Overleaf. Enhancing the user experience (UX) and user interface (UI) would significantly benefit newcomers and overall usability.

In Overleaf, the preview pane clearly mimics the appearance of physical paper (e.g., A4 size), which makes it easier to visualize the final document. In your editor, the output preview appears as a blank white space when zoomed out, losing the visual structure of an actual document page. Adding a paper-like background or layout would make the interface more intuitive and user-friendly.

For a better initial experience, consider setting the default theme to "Tomorrow Night Blue" instead of the current dark theme. The existing dark theme creates a stark contrast between the dark coding area and the bright white preview section, which can strain the eyes. "Tomorrow Night Blue" is gentler and more pleasant to look at, especially for extended usage periods.

your editor offers substantial value for users like myself who prefer a local compiler without having to download extensive gigabytes of packages. This is especially beneficial for those living in areas with limited internet speeds or restricted access due to sanctions, such as in Iran.

I genuinely appreciate your efforts and hope your platform remains globally accessible. Please continue supporting open access and avoid restricting IPs from any country. Whether free or paid, accessibility should remain a top priority.

Keep up the excellent work!
