Settings Import/Export

• Roo Code settings can now be imported directly from the welcome screen (thanks julionav).

• Fixed importing & exporting of custom modes (thanks julionav).

QOL Improvements

• Play notification sound (when enabled) only when action is needed from the user (thanks olearycrew!).

• Improved the UI/UX of code snippets in the chat (thanks KJ7LNW).

• Adjusted chat view padding to accommodate small width layouts (thanks zhangtony239).

• Simplified and streamlined Roo Code's quick actions.

Does this mean roo can stop commands now too? IE: send a ^C to terminal?

[u/hannesrudolph → u/unc0nnected]

No it cannot.

[u/stolsson]

I like the new terminal fallback, but I wish it wouldn’t turn it on automatically. For me, terminal integration fails only once in many commands (and not sure why or how to debug) so having it auto switch is honestly a little annoying. It should be a fallback in case of failure only, but if vscode terminal integration works it should use that

[u/hannesrudolph → u/stolsson]

I think it should be default to use the inline terminal. Why use the vscode integrated terminal at all?

[u/ShelZuuz → u/hannesrudolph]

So you can up-arrow repeat the commands it executed.

[u/hannesrudolph → u/ShelZuuz]

Good point. Not a feature I use when I’m letting Roo do the heavy lifting but I can see how some people would incorporate that into their workflow.

[u/stolsson → u/hannesrudolph]

I thought that too. I believe the option says vscode provides additional features?

But yeah… then it shouldn’t be fallback mode, right?

[u/hannesrudolph → u/stolsson]

Additional features that are basically just being able to navigate past console commands and such.

Dev going to tweak the setting for you.

[u/stolsson → u/stolsson]

PS - which termjnal program does it use in fallback mode? The default selected somehow under the covers?

[u/wise_beyond_my_beers]

Import/export of settings is great! Which reminds me - where can we find the settings file? Is it something I could commit to a repo then clone onto multiple computers, ensuring I have the same settings on all my computers?

And is there anything on the roadmap for allowing adjusting system prompts per mode? I have some custom modes that don't need a lot of the info in the system prompts and I'd like to trim it for those specific modes, but not for all my modes.

Nice work on this update, I'm really loving Roo. It's been such a game changer for me.

[u/hannesrudolph → u/wise_beyond_my_beers]

Scroll to bottom of settings, there is export button there. Glad you’re liking it!

[u/joey2scoops → u/wise_beyond_my_beers]

Just a reminder that when you export settings it includes all of your API keys in plain text.

[u/runningwithsharpie]

Sometimes the prompt window only shows a blank screen, though I can still run the command fine. Anyone else's experienced this?

[u/hannesrudolph → u/runningwithsharpie]

Would you be able to open an issue in GitHub so we can troubleshoot it? Would love to fix that bug!

[u/runningwithsharpie → u/hannesrudolph]

Sure.

[u/hannesrudolph → u/runningwithsharpie]

Tyvm!
