Inquiry: Native Outlook-style "Reading Pane" for Emails

[Kharg]

Hello,

This already exists as an unofficial extension by mozkomor



https://github.com/mozkomor05/espocr...view-extension

However it has not been updated since a long time.

I have created my own fork and I've made it compatible with the latest EspoCRM version: https://github.com/Kharg/espocrm-ema...view-extension

Hello EspoCRM community and developers,

Many of our users are migrating from traditional desktop email clients (like Outlook) and are heavily missing the "Reading Pane" feature (a combined view where the email list remains on the left/top, and the email content is displayed in a dedicated split pane alongside it).
Currently, clicking an email opens it in either the Detail View or a Modal window, which breaks the quick-reading flow and forces a lot of context switching when going through a large inbox.

I have two questions regarding this:
Is there any probability that a native "Reading Pane" (or a split-screen layout) for the Email entity will be introduced in the out-of-the-box self-hosted version in the future?
If this is strictly against the current unified UI philosophy of EspoCRM and won't be added to the core, what is the best/safest architectural approach to implement this via custom code or an extension without hacking the core frontend? Are there any recommended hooks or existing stable community extensions for the latest versions?

Thank you for your time and for developing such a great CRM!
