I haven't looked into the code yet, but my first thought upon seeing the attached images is that the opacity for the divider can be reduced, maybe to 50%?

@sanjai0py have set the opacity to 50%. Please refer to the screenshots above. Thanks.

Hey @iamsushantk

I am onboard with the idea that Dividers help improve visual separation and hierarchy within a layout.
Even with the added opacity for the divider, I think we would need further improvements to make the UX looks appear aesthetically clean. I currently do not have additional feedback on how to improve this.

At the moment, getting this implemented is a low priority given the current state of PR backlog. We will revisit this at some point later.

Something to consider in future is to use Native Menu provided by the OS. This https://github.com/usebruno/bruno/pull/1105/files#diff-06806ec8f9109775d07a5b223e78f2308d0811b7e78700305357adc7ec339a5d should give an idea on how to implement this

@helloanoop I am closing this PR and will look forward to proper implementation whenever that is planned. Thanks for your inputs.
