App builder upgrade, faster notebook loading & table improvements

New app builder with preview

Say hello to a whole new way of creating apps - now you can see your app take shape in real-time as you build it! See it in action in this quick video:

No more switching between tabs and refreshing to check your changes. Our new split-screen preview puts your notebook and app side-by-side, so you can watch your app come to life as you work. Building your app is as simple as clicking the display button on any block you want to include (or select multiple blocks at once). Use the dropdown next to the display button to show or hide code and outputs - your changes appear instantly in the preview.

We've also refreshed how you start building apps. Instead of automatically including all notebook blocks, your new apps now start empty so you can thoughtfully choose which elements to include. Don't worry though - if you want to add all your non-code blocks at once, there's a handy shortcut button for that!

Looking for settings or performance data? Find them easily with dedicated Settings and Analytics buttons.

Give the new app builder a spin and let us know how it works for you. And stay tuned - we're adding exciting new features soon to give you even more control over app layouts!

Faster notebook loading

Your notebooks just got a serious speed boost! We've rolled out performance improvements that make opening and switching between notebooks significantly faster - up to 7x faster, in fact. You'll notice the biggest difference with longer notebooks, so go ahead and load up those data-heavy analyses without breaking a sweat.

We hope you enjoy speedier navigation - and keep an eye out, as this is just the first of several performance improvements we're working on to make your workspace more responsive.

Data table upgrade

Your data tables just got more customizable! While we've been busy under the hood improving performance (notice how smooth column resizing feels?), we're excited to share some new features that give you more control over how your data is presented.

Now you can easily hide columns you don't want to display - just click on the column header and select Hide column. Need to check what's hidden? Click the eye icon next to the column header to view and manage all hidden columns. We've also added the ability to rename columns right from the header, and you can now reorder columns by simply dragging them in the header. All these new options make it easier to make your tables more readable for your audience.

Don't worry - these visual tweaks only affect how your data is displayed, not the underlying data itself. Perfect when you need to present your analysis in a cleaner, more accessible way!
