 ## Known issues
 - [ ] Currently, we rely on DragSelect to know which block gets selected. DragSelect seems to listen to the "blocks". However, it actually works by listening to the SVG path element, which is always a rectangle with some transparent parts forming a block. For irregularly shaped blocks, if you click on the transparent area that within the SVG rectangle, it will still get selected. (a mitigation has already been introduced in v0.1.4, but a proper fix should be that Blockly implements some kind of API, so that we can know for sure where the block actually locates.)
+- [ ] Currently, there is an issue related to the pointerdown event listener workaround for the setStartBlock gesture handling. The SVG root of a block that has a next block overlaps with that next block. So, when we try to remove the pointerdown event listener for the next block, it does not matter as the pointerdown event listener for the parent (higher level) block is still present. (a fix may be introduced when the Blockly team introduces proper gesture handling for setStartBlock.)

+### Note on keyboard navigation plugin
+Currently, the keyboard navigation plugin has no compatibility issues with the multiselect plugin. It is enabled by default
+in the test files. However, one thing that developers and users should note is that the regular Blockly core's copy/cut/paste shortcuts 
+and multiselect plugin's copy/cut/paste shortcuts are completely disabled when the keyboard navigation mode is turned on. This was assumed
+to be the expected behavior of the user as it defeats the purpose of having the keyboard navigation mode turned on and the user would try to
+select blocks using the cursor and copy/cut/paste with that selection. However, if a developer wants to allow for either copy/cut/paste behavior
+(Blockly Core or multiselect plugin) while the keyboard navigation mode is turned on, we would have to make the following changes described in this
+[issue](https://github.com/google/blockly-samples/issues/2424).
+
+### Note on disable top blocks plugin
+The disable top blocks plugin has to be initialized after the multiselect plugin. The main reason behind this is that 
+the multiselect plugin has its own custom context menu, which allows for the disabling of any blocks (not just top blocks).
+Installing the multiselect plugin after the disable top blocks plugin overrides the disable top blocks plugin's context menu
+customization. If we install the disable top blocks plugin after the multiselect plugin, everything works as intended.
