Yes elementary-tweak work very well with Hera's release.
I have it and I have no problem with. Like say @Bo_rislav :
Of course if you set a broken theme or something the layout will be
broken but the os will not be destroyed if this is what you ask.
Here the link to the Github's project :
GNOME Tweak tool is designed for GNOME, a desktop environment that is not shipped with elementary OS. While elementary OS does use some of the same components and thus settings as GNOME, not everything is similar or compatible.
Installing GNOME Tweak Tool pulls in a couple of dependencies from GNOME: gir1.2-gnomedesktop-3.0 and gnome-shell-common. These are ...
Yes it is usable, personally I would install then remove the ppa:
# Make sure you have software-properties-common
sudo apt install software-properties-common
# Install elementary-tweaks
sudo add-apt-repository ppa:philip.scott/elementary-tweaks
sudo apt install elementary-tweaks
#Remove ppa connection
sudo add-apt-repository --remove ppa:philip.scott/...
This will reinstall the default icons and theme:
sudo apt install --reinstall elementary-theme elementary-icon-theme elementary-default-settings elementary-desktop
Also try this: System Settings -> About -> Restore Default Settings
sudo apt-get install dconf-tools
You can change values here. Not all windows are effects. Looks like not allow windows can change shadow settigs from this location but many applications do pick up shadow settings from here
Just install Elementary Tweaks. Here you can learn how to install it. With that, you can set the double-click behaviour and the location of the window control buttons.
Once installed, go to the system settings->Tweaks and there you'll find what you're looking for.
I can't tell you what will happen. Probably you will be able to install it but it won't change anything since elementary OS uses the Pantheon desktop and not Unity.
In case you want a similar app for elementary OS, there's one called elementary tweaks.
To install it you just need to:
sudo add-apt-repository ppa:mpstark/elementary-tweaks-daily && ...
actually, at least in my case, selecting "Prefer dark variant" under the "Appearence" tab of Elementary-tweaks works globally for every application
You just need to install elementary tweaks as explained here - see here for installation instructions
See a screenshot taken a while ago
You have to update elementary-tweaks package also in order to work with Hera. When the update to Hera was released, elementary tweaks behave like you explain, but after a while it was updated also and now it works as before, only slingshot options for raws and columns are missing, because it was removed from the OS, only 5x3 grid is presented at the moment. ...
Yes, they works. The developper pretend that the way they are built is safe for the sysytem, as long as I know there is no any harm for the system by using elementary tweaks. Of course if you set a broken theme or something the layout will be broken but the os will not be destroyed if this is what you ask.
