### Bug description

The client "Nextcloud Settings" window has changed functionality recently. The most noticeable aspect is that there is a new tab bar with "Standard file sync" and "Connection settings".

a) The "Connection settings" tab is redundant as it is a duplicate of the "Network" button above.

b) Adding a new tab bar is a vertical space challenge for those with several sync folders. Each sync folder is much higher than it needs be with a large green tick (or other) and three lines of text. The height of each connection could easily be be halved without reducing font size. For instance, the line "Synchronizing files in local folder" does not add useful information for the user (it is a lie anyway, because synchronization is not in progress, but rather waiting).

c) When synchronization is in progress, the content has changed. It used to give useful information like estimated time to completion. But now it gives different information, like speed of transfer. I'm not interested in the speed, but I am interested in how long I have to wait. Could we revert to the former, please.

d) The information about position in the queue to be sync'd has been dropped.

e) The concept of "Nextcloud Settings" is wrong, or at least only one side of a coin. It does provide an
interface for adding sync folders -- a setting. But most of the time is acting like a monitor. I can see at a glance if all my folders have been sync'd (all green ticks) and therefore safe to power off my machine,
or alternatively, safe to start an application in a given sync folder after power up. This is particularly important if I am off-site using my laptop with synchronizing over a low speed internet connection; I expect all files to be where I left them on my laptop to be present on my desktop when I return.

f) There is something wrong with the "window" presenting these "Nextcloud Settings". It is partially like
a pop up dialogue box, though it should be like any other window with "minimise" and "maximize" buttons on the title bar. It should be possible to launch this window from a regular icon or shortcut, or even automatically upon startup, but as it is I have to wait for all the tray icons to settle, then locate the nextcloud icon, then select "Settings" (as opposed to "Monitor"). A right nuisance.


### Steps to reproduce

1. After starting a machine, wait for ages for all the tray icons to appear, settle and become responsive.
2. Rt-click Nextcloud tray icon | Settings
3. "Add Folder Sync Connection" for several different/independent folders, observe the limit is about 10 before only some of the sync folders can be monitored simmultaneously.
4. Click on "Network"
5. Click on "Connection settings" tab, notice same contents as 4.
6. Observe reduced information showing as a particular folder sync is in progress.
7. Observe no n'th in queue information.

### Expected behavior

Previous behaviour with useful progress information.
No superfluous information that reduces vertical space needed for monitoring several connections.
A proper "Nextcloud Monitor" window with minimise, maximise, launch from shortcut.
