Construction Notes Manager follows your current text style and dimension variables where possible. You can customize text entities inside blocks by editing the blocks.
You can make Construction Notes Manager follow your layer name, color, and linetype standards by 1) editing the LAYERS.DAT file found in the Construction Notes Manager folder and 2) editing any blocks as needed. If you edit the LAYERS.DAT file, you will probably want to protect it from later being overwritten. You can do this by creating a folder for your team or yourself, placing it above the Construction Notes Manager folder in AutoCAD's Support Files Search Path, and putting your custom LAYERS.DAT file there so it will load instead of the Construction Notes Manager vanilla LAYERS.DAT
Construction Notes Manager uses several blocks. You can of course edit the blocks to suit your needs. If you edit any blocks, you will probably want to protect them from later being overwritten. You can do this by creating a folder for your team or yourself, placing it above the Construction Notes Manager folder in AutoCAD's Support Files Search Path, and putting your custom blocks there so they will load instead of the Construction Notes Manager vanilla blocks
You can do much to customize the key notes table by editing the NOTEQTY blocks in the program folder, then saving them to a folder of your own. You can add or remove lines or change layers or colors. If you change the width of the key notes table by editing the NOTEQTY blocks, you must tell Construction Notes Manager the new width (so it can do multiple columns of key notes properly) using the variables shown in the CONSTNOTPOWER.TXT file found in the program folder.
You can change the column widths and line spacing of the quantity take-off table by using the variable settings found in the CONSTNOTPOWER.TXT file found in the program folder.
