Version 1.0.7 brings the much-requested grid view feature, which you can activate on the pause screen and customize in the settings screen, as well as several bugfixes and quality of life updates:
Tower of Destiny room changes:

• Under Fire: Added a pit tile and a wall tile to reduce dead end possibility space

• Added grid view. Toggle in the pause menu during gameplay, and adjust the style and opacity in the settings screen.
• Changed audio APIs on Windows from WaveOut to XAudio, if available; audio playback should be more consistent as a result. In the event of audio issues caused by this, you can use the new "--force-waveout" launch option.
• Hot coals now glow brighter when something on them is in danger of getting burned
• Exiting an uncleared room now requires a deliberate input; repeated inputs will halt at the room boundary to prevent accidental exit
• Added an option to the Select World screen to open the world download page in your default web browser
• World revision number is now shown on select world screen
• Minimap icons for rooms that have been visited on a previous playthrough but not the current one are now more faded
• One-way ladder destinations are now shown in the target room with a shadowy ladder graphic

• Tall grass, cattails, and curtains can now coexist with trapdoors and toggle floors
• Toggle doors can now coexist with trapdoors
• Testing a room or world now anchors the current floating selection, if any

• Fixed a crash on Windows 11 that occurred after importing multiple replays
• Fixed memory errors and possible crashes in some edge cases when using single-room replay mode or restoring to the end of a replay
• Fixed mouseover not being hidden when climbing a ladder
• Fixed an incorrect visual effect being shown when Leaf bumps into statue rubble
• Fixed tile inspection pop-up appearing at the wrong time
• Fixed incorrect game state (potentially resulting in a crash) when playing a replay while in single room mode
• Fixed a bug allowing keys to be picked up while Leaf is at a different elevation than the key
• Fixed closing monster gate not clearing poison trail
• Fixed ladder travel being able to place the player inside solid objects or monsters
• Fixed waypoint travel being able to place the player inside monsters
• Locked doors now block waypoint travel while closed
• Selecting a world with the "Select" option on the Select World screen now sets it as the current world for editing (if editable), not just for play
