5755### The monitoring sidebar

5957**Tasks**, **Logs**, **Protocol**, **Network**, and **Console** form a *monitor group*. Pin the group and they leave the tab bar and move into a resizable right-hand column, so you can watch traffic while working in Tools or Resources. Drag the column's edge to resize it, from 320 to 720 pixels wide. The column width and the selected monitor tab persist across reloads.

9086A footer at the bottom of **Server Settings**, **Client Settings** and the **Add / Edit / Clone server** dialogs names the secret store in use, so you see it where you type a secret. It turns into a warning when secrets are memory-only (lost on restart), in an unencrypted file, in a file with loose permissions, or in a file that can't be read.
