[Feature] collapse "Connections" tab

[ThuanDoHung]

Hi,
I use screen with "portrail" mode (1920x1080), when use tab "connections" can not collapse, i feel hard use.

WANT:

• When connected with server, tab "Connections" close/collapse to left (may be show prefix domain/ip), show larger tab message.
• When hover topic subscribe, it show minipopup, but minipopup cover topic above can not click to topic above --> I want if mouse out topic then popup hidden.

@ThuanDoHung Hi. Indeed, this has been a long-requested feature. We have implemented flexible resizing and hiding in version 2.0, but as 2.0 has yet to be ready, I will work on optimizing this issue in the upcoming 1.9.x versions. Thank you for your feedback.
