Besides the timeline buttons and color switch button being ready to have their changed shortcuts (when we implement them for these buttons) in their hint tooltips, there is no new functionality. This is merely to make the lives of translators easier.
This is the final commit of weird string IDs being replaced to actual sentences in Translations.pot
Caused in CreateNewImage.gd, Global.current_layer = 0 should be under Global.canvas gets set to a new canvas, and after its _ready() method gets executed. The crash occurred when a layer above 0 had transparency less than 100, and a new image was created. _on_OpacitySlider_value_changed() in AnimationTimeline.gd was executed on the old canvas right before it was destroyed, while Global.layers had been cleared.
Also removed _on_OpacitySlider_value_changed() from Main.gd, it served no purpose there.
When the user clicked on a layer container to change its name and then clicked away, the program crashed. This was because the name of the layer was changed (`Global.layers[i][0] = new_name`), and Global.layers_changed() was being called, which removed all of the layer container UI and re-created it.
This is unneeded to happen when only the layer name changes, so I added a boolean to skip the execution of the method.
Oddly enough, the crash was not happening on Windows (at least on my end) and it was working as expected. Godot's output terminal was not showing any error messages, either.

* Last fix
* Added translation strings
You can add tags by right clicking on a cel and selecting "Add Frame Tag". No tag modifying and deletion is implemented yet.
I'm using a different ScrollContainer for the tags, which gets updated everytime the main timeline ScrollContainer gets updated. I hide its sliders from its theme, wish there was a more straightforward way.
If the user chooses a brush that is not the pixel or a circle brush and uses the bucket tool, the brush image is used as a pattern that fills the area.
The onion skinning button replaces the old onion skinning area of the timeline, but there's no way right now to change the settings. This will be added in a future commit. More UI changes will soon follow.
Tabs are now included as Class items in all themes, the OK button in ExportDialog appears on the left on Windows machines, and on the right in all other operating systems. Also added border outlines to all window dialogs.
