Builds 369 to 374 were focussed on performance tuning.

The results are as follows:

• Overall performance improved 2x to 3x across all four browsers tested
• Zoomed Out performance is now constant regardless of how far out you zoom
• THEMEs without cell history perform about 1.5x faster than those with history
• ZOOMs >= 1 perform about about 1.5x faster than ZOOMs < 1
• If you want performance on Windows use Chrome

When I'm clearing LifeHistory states should that include state 6?

rowett wrote:When I'm clearing LifeHistory states should that include state 6?

Probably yes. There are at least two kinds of useful LifeHistory "clear" operations, though:

1) Clear just the blue state-2 envelope cells, leave marked cells and state-6 cells in place.
2) Convert LifeHistory to plain Life, changing all odd-state cells to ON cells and all even-state cells to OFF cells.

There might be a third, I suppose:

3) Remove the markings on marked cells, so state 4 goes to state 2 and state 3 and 5 go to state 1. State 6 would probably be left alone in this case, since it's not technically a marked cell.
3b) I wouldn't mind if state-6 cells just disappeared when cells got unmarked, though... or "state 6 only" could be a fourth type of clear operation.

Maybe a hotkey could be assigned to one of these, and Shift+hotkey or Ctrl+hotkey or whatever to the other(s)?

OK I think three out of four are already implemented:

1. Clear just the blue state 2 (History) cells: select drawing state 2 (Ctrl-2) and then clear cells that are the current drawing state (Ctrl-Alt-K)
2. Convert [R]History to plain [R]: (Ctrl-Del)
3. Remove the marking on marked cells. I'll have to add something for this.
4. Clear just the grey state 6 (Kill) cells: select drawing state 6 (Ctrl-6) and then clear cells that are the current drawing state (Ctrl-Alt-K)

If you think it's worth adding a single key hotkey for items 1 and 4 please let me know.

Build 386 is now available on the lazyslug server

Enhancements in this build:

• hotkey Alt+"Del" to clear [R]History marked cells
• hotkey "Esc" will cancel a Pick or Replace

Now on hotkey Alt-Del.
.... Ctrl-Alt-Del wasn't available

Sounds good! No, your two-step method is definitely better -- more memorable and more versatile.

Build 387 is now available on the lazyslug server

Enhancements in this build:

• Generations rules now have brightness shading when using layers
• performance improvement for THEMEs without history
• added another alias
• START indicator now toggles AUTOSTART if defined
  • hotkey Alt+"O" to toggle
  • if START disabled when LOOP defined then playback stops when Loop happens at T=0
• STOP indicator now toggles STOP if defined
  • hotkey Alt+"P" to toggle

Fixes in this build:

• toggle LOOP when defined (hotkey Shift "P") wasn't working
• take screenshot (hotkey "O") was not working

This build is a Release Candidate.

I've discovered that the forum uses various hotkeys itself that conflict with some on LifeViewer. How these hotkeys are triggered depends on the browser. On Chrome it's Alt+<key>.

These <key>s include:

• h - go to Board index
• p - Print view
• u - go to User Control Panel
• l - Logout

Do you think anyone uses these hotkeys?
If not could Nathaniel remove them (or I can programmatically do it from LifeViewer)?

EDIT: The Wiki also uses hotkeys: same question.
