Really interesting project, I like how you’ve handled the resizable split views—clean idea and very practical for building flexible UIs 👍 It’s cool how layout management often comes down to precise control over dimensions and proportions. Even small percentage-based adjustments can make a big difference in how a UI feels and responds. I’ve run into similar situations where calculating percentages quickly helps when planning layouts, and I sometimes use simple tools like https://calcolopercentualeonlinee.it/ for that. Nice work overall, this looks really useful for devs building dynamic interfaces
