The launch config feature of warp is extremely useful to bring up a whole bunch of terminal sessions running with the stuff I use rather than going through the tedious process of bringing them up everytime I start my pc, but I would also like to define custom splits, rather than just vertical or horizontal I would like to define percentages to allow for custom tilling of panes even further, how do I do it? and is it even possible? I ask because the docs do not mention anything in regards to this (https://docs.warp.dev/terminal/sessions/launch-configurations#tab-macos)
OS: MacOS 15
warp version: v0.2025.06.11.08.11.stable_01
#Defining custom pane split in the launch config

Hi @opal stirrup. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
At this time, Warp's Launch Configuration feature allows you to define split panes with either vertical or horizontal splits, and you can nest splits to create more complex layouts. However, the documentation and available knowledge sources do not mention any support for specifying pane sizes as percentages or custom ratios. The split direction can be set, and you can nest splits, but all splits are divided evenly by default.
This limitation has been noted by other users as well, with feature requests specifically asking for percentage-based sizing for inner panels and more advanced layout control. As of now, these requests are open and have not been implemented in Warp. You can see an example of such a request here, where users express the need for "% based sizing for inner panels" and more configurable layouts, but there is no indication that this is currently possible or supported in the product or its documentation More configurable launch configurations.
So, to answer your question:
No, it is not currently possible to define custom pane sizes (such as percentages or ratios) in Warp's launch configurations. All splits are equal, and the only customization available is the split direction and nesting. If this is an important feature for your workflow, you may want to upvote or comment on the related feature request to help signal its importance to the Warp team.
