# User Preferences¶

There are only a few options located in the Preferences, accessible though the menu via Edit > Preferences. Most other options, like whether to draw the grid, what kind snapping to do or the last used settings when creating a new map are simply remembered persistently.

The preferences are stored in a system-dependent format and location:

 Windows Registry key HKEY_CURRENT_USER\SOFTWARE\mapeditor.org\Tiled macOS ~/Library/Preferences/org.mapeditor.Tiled.plist Linux ~/.config/mapeditor.org/tiled.conf

## General¶

Include DTD reference in saved maps
This option is not enabled by default, since it is of very little use whereas it can in some environments cause problems. Feel free to enable it if it helps with validation for example, but note that the referenced DTD is likely out of date (there is a somewhat more up-to-date XSD file available in the repository).
Reload tileset images when they change
This is very useful while working on the tiles or when the tiles might change as a result of a source control system.
Open last files on startup
Generally a useful thing to keep enabled.
Use safe writing of files
This setting causes files to be written to a temporary file, and when all went well, to be swapped with the target file. This avoids data getting lost due to errors while saving or due to insufficient disk space. Unfortunately, it is known to cause issues when saving files to a Dropbox folder or a network drive, in which case it helps to disable this feature.

### Interface¶

Language
By default the language tries to match that of the system, but if it picks the wrong one you can change it here.
Grid colour
Because black is not always the best color for the grid.
Fine grid divisions
The tile grid can be divided further using this setting, which affects the “Snap to Fine Grid” setting in the View > Snapping menu.
Object line width
Shapes are by default rendered with a 2 pixel wide line, but some people like it thinner or even thicker. On some systems the DPI-based scaling will affect this setting as well.
Hardware accelerated drawing (OpenGL)
This enables a rather unoptimized way of rendering the map using OpenGL. It’s usually not an improvement and may lead to crashes, but in some scenarios it can make editing more responsive.
New in Tiled 1.1
Mouse wheel zooms by default
This option causes the mouse wheel to zoom without the need to hold Control (or Command on macOS). It can be a convenient way to navigate the map, but it can also interfere with panning on a touchpad.

## Theme¶

On Windows and Linux, the default style used by Tiled is “Tiled Fusion”. This is a customized version of the “Fusion” style that ships with Qt. On macOS, this style can also be used, but because it looks so out of place the default is “Native” there.

The “Tiled Fusion” style allows customizing the base color. When choosing a dark base color, the text automatically switches to white and some other adjustments are made to keep things readable. You can also choose a custom selection color.

The “Native” style tries to fit in with the operating system, and is available since it is in some cases preferable to the custom style. The base color and selection color can’t be changed when using this style, as they depend on the system.
